What's it about then? Race? Gender? Religion? All i'm saying is that painting in broad strokes like that AND THEN discounting available resources as unimportant is incredibly counter productive. If we use the Oxford definition of privilege: "A special right, advantage, or immunity granted or available only to a particular person or group". In today's day and age what would be the singular most important factor in gaining "right or advantage". Well money of course.
And cultural appropriation? What is it then? I'm not talking about shite like black face here, because that's simply inappropriate. People argue that reducing a culture to stereotypes is harmful and offensive, but that's not just true. Stereotypes and prejudices is just how the human mind works, that does not mean that sterotypes and prejudices are harmful or offensive by default.
If you asked me what i think about the French and i answered: "Well, they enjoy their wine, cigarettes and cheese". That's an incredibly stereotypical statement right there, but it's hardly offensive. If you dressed up in a thin mustache and a beret for Halloween, again, very stereotypical, but i doubt the french would be any offended by it
The disconnect you're currently finding is that you're applying dictionary definitions to sociological situations. That's not going to help you understand at all.
What I will tell you is that I've felt the weight of being a person of colour in an overwhelmingly white upbringing (I grew up in South East Wales - literally the only person of colour at the entire school, until I moved to Surrey at the age of 13 and became one of the only 3 black people in my year, and I could count on two hands the amount of people of colour completely)
When I first heard the term I understood completely what it meant, and I didn't need a dictionary to tell me otherwise.
It's situations for example where I would be scared to go into shops by myself because I knew I was more likely to be followed than everyone else.
Only seeing black women like myself being depicted as ghetto baby mamas, "the help", generally being fat and or ugly, uneducated etc in tv and movie roles.
Being told that the way my hair grows naturally out of my head is a political statement that could be used against me in situations such as job interviews.
The oxford dictionary won't tell you that, and again it has nothing to do with wealth, my family are considered middle class and I still face these situations and many more.
There's also this piece written in the 80s if you want more examples:

As for cultural appropriation - you were on the right track with the erasure of cultural identity.
It's more so to do with the simplification of people's culture, and reducing it to a costume.
For example in my culture wearing the Kente cloth is significant because it's part of the history of the Ashanti Empire, known today as Ghana. Made of silk, worn by royalty and woven by hand each individual design is unique, and tailored fit for the individual. You can identify where someone comes from by their Kente cloth alone, patterns have individual meanings and proverbs - I could go on but you get the idea.
Now if you were to visit Ghana, there's dozens of trade stalls intended to sell to tourists and foreigners with the aim of learning more about the history, and being a part of it's historical significance - that is cultural appreciation. Which is part of trade, increasing knowledge and culture and has been around for thousands of years.
Cultural appropriation comes in when you strip the historical, indigenous, or religious significance of something in order to make mass marketable, and reduce people of colour to stereotypes or costumes.
It's not always intentional, but it can be hurtful or insulting, and the fact that this has to be explained is kinda the point.
I personally believe everyone has the freedom to express themselves however they wish, but using cultural symbols to satisfy a need for personal expression blurs the lines.
Now I don't believe that dressing up in fancy dress is intentionally insulting, but a lot of it does depend on racial stereotyping - most people don't think of the implications of dressing up as an Arab, or a Geisha, or a Mexican in a sombrero, I mean why would you, it's funny, or fun, or sexy so these implications don't affect you. Mostly, racially, ethnically and culturally based costumes are intended to be one of two things - humorous or erotic. What is it about these people that is funny? (especially if they were killed as a result of their culture - e.g. Native Indians) Nothing is. It's dehumanising people who were already marginalised by society, reducing them to offensive caricatures in order to make our friends laugh, to make us feel more exotic, or in order to make ourselves look hot.
I could go on but you get the general idea.
Like I said it's not always intentional, but the mere suggestion that it's a 'faux issue' is simply false, if you'd like to know about both issues then by all means send me a message.
