While I actually agree with this, it's basically an admission that notions like equality and fairness are unreasonable standards, at least when it comes to life as a whole. Our inceldom is just one facet of a fundamental problem with existence, specifically that to "have" or possess something, then someone else must not have it. The world that you're asking for is one where life bears no energy cost, and it's simply an impossibility.
Do I think it's reasonable that other people (not to mention animals) have to live in destitution to ensure my comfortable life in the west? No, but what exactly can I do about that? Even if I ruled the world, all that could be done is to change who or what has to pay the suffering cost of existence, or change when exactly it must be paid, but the cost would still remain. You can't alter human nature, you can't increase the material wealth of the planet, you can't convince people to stop creating scarcity/have them heed your advice by their own choice, and you can't change the fact that you can only improve life insofar as to mitigate problems caused by it's own existence/that there is no actual positive utility.
Ultimately, if you feel that denying women the freedom of choice in their mates is unreasonable, then you shouldn't be willing to accept any of the rest of this either, and I'd even agree with you. But you have to realize the implication of what it is that you're saying, it's not a principle of striving towards an equal world, rather it's the rejection of any sort of life at all.
