Stupid libertarians think coercion is all that matters. But if someone up-river from you consumes all the water then you are their victim even though there is no coercion. So this should be considered a crime and the victim should be compensated for damages.

In the same sense, the victims of sluts are incels because sluttiness causes an unequal distribution of sex. Just as in the river example where the victim is denied water, sluts cause incels to be denied sex. So sluttiness is a crime and sluts should be forced to provide free sex to all men as compensation.

On the other hand, prostitution has no victims. In fact prostitution has many benefits and all productive societies in history tolerated prostitution. Wherever prostitution is not tolerated, men stop being productive.
