I mean it is true to an extent, it is just treating consent as an absolute and not a spectrum. Power imbalances absolutely impact where that needle is.

I've had lots of sex like "yes please". I've had sex where I was like "ill probably enjoy enjoy this" or "I genuinely don't really care one way or another and it will please my partner" (who I'm not vulnerable to in a societally enforced way) and all of them would fit the binary of consensual but are at various points on the spectrum.

The last example is an illustrative example where it would clearly fall at different points on the spectrum if I was more or less dependent on/vulnerable to my partner.

Sex negative feminism had some points that were correct to some extent, sex negative and sex positive feminism both synthesized into a more sex neutral position for a reason.

Yeah it does and you couldn't really change it. As women would act based on internalized sexism and even if a man wants to respect the wish of a woman and give her 100% control, she would act in the sexist norms, which would signal to the men that women want those sexist norms. So men would continue to "enforce" those norms as women would fear to stop the men.

So sexism can't be solved; and then we can ask why bother trying to change it then?

Stupid line of thinking that is insulting to both, women and men. No means no, my friends. No means no. Respect your fellow humans.

Clearly what we need to do is a bunch of gene editing so that humans go through a cocoon phase where they sexually mature and emerge as a fully-formed adult.
