Urusei Yatsura, Your Lie in April, Tatami Galaxy, etc. There's plenty of well-respected romantic anime, including a lot of girl-coded stuff, and they even usually have an element of self-insertion or escapism to them. But they don't define themselves entirely around vicariously experiencing perfect love. That's the difference (and genuine question for people who think the image in the OP is wrong, how much of the audience for Komi-san do you think feels romantically satisfied in their real life?)
Whether it's in stupid harem isekai or throwaway high school romcoms, everyone realizes on some level that escapism – i.e., literally and deliberately ignoring reality – is not something that should be celebrated. It's surprising that in an imageboard for "leftists" no one in this thread has attempted to question the dynamic of studios making tons of cash by selling temporary relief from the crisis of loneliness that affects all demographics in current society
Instead of media that makes you briefly feel less lonely, why don't people make media that actually helps people -be- less alone? Media that shows the commonalities between people instead of encouraging misanthropy, that gives lonely people the courage to actually put themselves out there, that helps people understand each other instead of presenting idealized smoothed-over characters that don't resemble actual human beings? So much media today just feels like it breeds further isolation between people, why defend shit that encourages its audience to dig themselves deeper into the "2D>3D" hole?
But oh yeah you're not actually supposed to think about media on any level beyond just "I like it/I don't like it" - guy who's probably in another thread right now proclaiming himself to be the only real Marxist who ever lived
