I don't agree with much of that really.
I'll ignore the final point about money distribution as that's just the usual 'why should the wealthy have more, give it to the more needy' argument that is more a continuation of a class / societal debate than a specific football competition one.
I don't agree that a lower league club like Tamworth had less of a chance of winning that tie by playing 30 mins ET and maybe pens at their ground, rather than starting a new match from minute one away at the PL ground. From the money / business side, it's an extra money spinner, yes - but from the sporting side, there's more of a chance of an upset finishing the match on the day at the lower teams 'leveller' of a home ground than them winning a new match away from home.
And I don't agree that teams should be able to switch things between themselves - like the draw (switching to the big teams ground for financial reasons), or decide between themselves whether it's a replay or not. The rules should be in place and it shouldn't be up to the teams to manufacture them.
Personally, I don't see why VAR can't be used in matches where they have the facilities. But I keep hearing this idea that the same rules should apply to everyone in the round for fairness. So, if we're going down that route, I don't think we should be introducing things whereby certain ties can decide between themselves which teams play home and away, while other ties can't. I know that isn't a quote from your post, but it's been another similar idea suggested a lot on here that goes along with the kind of things you were saying Rory Jennings suggested.
So many of these suggestions are turning the ties into a manufactured negotiation and I don't agree with any of it - just keep it how it is. The open draw is made, and it's the luck of the draw whether you play a tougher or easier oppenonent, and whether you're home or away. It really shouldn't be up to clubs to be able to 'sell' home advantage (either from the start or after 90 minutes) for a money boost or anything like that.
