Eh.

1. Even dirty, slutty women don't like constantly being give death and rape threats.
2. There are not enough slutty women to meet demand. Even if a woman is banging 3 guys per day, either her roster will fill up instantly or (if she never bangs the same guy twice) the guys she has alreadh banged will be back in the market an hour after they blow their loads.
3. Slutty women might want to fuck a lot, but they still have their preferences and will exercise them. Why fuck the overweight, balding McDonald's worker when you can fuck a finance bro with a six pack and a razor-sharp jawline? And if you are that finance bro, why would you be on an app with so few women (as per, (2))? Most women will gravitate towards platforms where they feel safe and respected (wrt normal cultural norms regarding sex), so the hot guys will be spending their time on these platforms since they are largely ambivalent to anything except the existance of a suitably large and attractive female population.

I'll note that this is essentially the dynamic at play on fetlife. We already have a real life example of how this works out, and no, it is not a utopia of abundant pussy for every horny dude, but rather the opposite - fetlife is well known for having worse outcomes for straight guys than mainstream dating platforms, because women simply don't respond to (almost any) messages on the platform.
