Haaland has scored nearly 300 goals by 24, yes injuries and a sustained drop in form are possible but he's well ahead of the curve. He is on a Champions League pace that nobody has ever set or close to it.
Yes Muller wasn't considered as good as Beckenbauer back then, or a genius but Muller still won a Ballon d'Or, second once and third twice. 10th in France Football's best players of the 20th century. Haaland may never be Messi level with his style of play but he could be in the top 20 all-time like Muller due to his scoring ability. It will probably depend on trophies and big-game performances. He has a long time for those to come yet. I remember a time when Cristiano Ronaldo was criticised for not being a big-game player.
The more important post you didn't quote was the other one...
Anyway the important thing in the post you've quoted it's that Erling will enjoy the tendencies of his period and that would help him to be more remembererd if he keeps his records, while at the same time, he needs to keep those records afloat for many seasons in order to be named in such lists and for that "life" has to help you.
So it's not that much a question of better quality: equal better stats, or demerit another player quality because he doesn't have the numbers of an Erling. Of course better stats to the very list assures any player a constant place in the books. Nobody doubts that, this leads to..
...Erling depending excessvily in those numbers, even more than Muller (that BTW it's a player that I preffer over Erling, with more atributes than the Norwegian in my view) and Muller had the curse (because of the ultimate pression implies to deliver for Germany)/and at the same time advantage of playing for Germany and win WCs, that gives an extra aura too.
All in all, with every legendary player that this game had produced with more focus in his goalscoring than anything, being closer to current times helps quite a lot and is more important than in other cases like for instance a Best, Charlton, Di Stefano, etc...the most modern versions of the greatest pure goalscorers tend to overlap the older ones, that has happened even with all rounders phenoms and awesome goalscorers like Puskas, that sometimes he is not even mentioned, a lot more with someone like Bican and such that makes Erling's and others players mentioned here records look pale.
