If every average man dropped out of the dating market it would not affect women one bit. Their dating problems are entirely based on the behaviour of top tier men

All that would happen if the average man dropped out of dating entirely is that women would complain less about harassment and unwanted attention.

That's it.

They have nothing but apathy for average men.

Their "problems" are entirely based on high tier men not committing to them.

That's it. That's literally the vast majority of their problems. So if the average man left the game, the only difference it would make is no more unwanted attention. It wouldn't make dating easier or level the playing field at all.
