You realize that you cannot and will not stop people from spending money on vtubers because of parasocial connections, right?
Even if you make publicized relationships common, they will receive the same amount of money, from the same amount of people, for the same reasons.
The state of men giving money to women for appealing to them and men spending money on women for being women is a constant state of the universe. It cannot, will not, shall not change.
You could literally force every single man to become a Chad right now and it would still happen, because it is the natural state of the universe for men to give women money. It will course correct somehow.

The only choice you get is to whether you want thousands of men to be willing cucks or not. You don't get to choose a world where men don't give money to women expecting them to like them. That world isn't something that's going to happen. You can keep this a world where men dislike whores, though.
