This is all hypothetical feds
The main proposed "silver bullet" solution are sex robots, which if able to atleast replicate the appearance of emotion would make foids obsolete, although I don't think we're anywhere near realistic sexbots. Maybe in a few more decades, 2050. Although I'm personally skeptical of these advancements.
In the meantime, if we wanted to implement actual changes then we'd have to launch a social revolution to basically abolish gynocentric social practices (reverse sexual revolution). I don't think there is any solution to foids under current modern Western systems. While I don't think traditionalism fully addresses the concerns of incels and it has inherent gynocentric values, a return to familial-clan systems which enable arranged marriage. It will atleast return the sexual market from the current foid monopoly back to a practice of men trading their daughters based upon SMV for other benefits (arranged marriage was historically basically used for families getting some financial or social benefit for letting jr sex their daughter). You'd also have to introduce punishments against adultery and dissuade divorce.
Another, more modern, solution in my view could be state-mandates girlfriends. I know people bring this up a lot without elaborating so this is how I see it. Women would be paid on a government contract to be the partner of incels. They could be matched by a computer based on a variety of factors including look-matching and actual "compatibility" factors (eg: ethnicity, religion, lifestyle) or just by sortition. Women on s[UWSL]uch a contract would have relatively more rights than women not on one who'd basically be low-class citizens. The women would be required to adhere to the contract, so no cheating, sleeping around, etc, or they would both lose those rights and be punished. You could monitor this by having their male partners log info about how the foid treats him (might violate the guys privacy though). Also the state could then reward obidient foids who stay in shape for their husband, have sex with him regularly, be nice with him, etc.[/UWSL]
[UWSL]Elliot also had his own system in his manifesto, but it might be either to extreme or to idealistic for some people.[/UWSL]
[UWSL]in general though for any change, women would need to lose power. You could also bring back sexual slavery (in Minecraft, no I dont support this) or something and have incels buy and sell GFS on a market.[/UWSL]
[UWSL]Society would 2000% need to be patriarchal, without any gynophile or gynocentric elements.[/UWSL]
