I honestly do not get takes like this, at all. We live in an era where more games are released then ever before and I can't even process how most people have the time or money to play everything that comes out in a given year. Remasters/remakes are just one of several kinds of games released in an annual basis and you could easily spend over $1,000 on new games in a given year and not buy a single remake/remaster/enhanced port.
Also the idea that a game is somehow worth less because it's old is also really sus. Gaming has been a passion of mine for basically all 33 years I've been alive, and there are tons of games where a remake/remaster is either a game I've never heard of, or a game I never got around to playing. Many of these remasters also go out of the way to fix problems with the original version that your suggested "a 90% emulated port is good enough" don't address. This doesn't even address situations where a remake/remaster enables a previously untranslated game to finally get an english release like we've seen with the Famicom Detective Club series and the Great Ace Attorney games.
I think that's their point that they'd rather there be more new ideas in the industry, rather than recycling the same ideas, since there's so many games already on the market that remasters and remakes always fade into obscurity.
I would argue that a lot of remasters are cashgrabs that realistically can be "fixed" in the eyes of most people with a few emulator tricks like forcing 16:9 for 3D games, texture hacks, forcing higher resolutions. And that's only if you really need to, most of the time the games are perfectly playable as they are.
Not to mention that most remasters and remakes very very often either don't bother to change anything about the original (Secret of Mana remake) or introduce their own problems and challenges (Silent Hill HD Collection, Crysis Remastered, Mafia 2 Definitive edition, Pokémon BDSP, Pokemon LGPE, Devil May Cry HD collection, Diddy Kong Racing DS, GTA Definitive Trilogy, the list is never ending...), that basically make them redundant and throwaway releases since they're sidesteps or worse compared to the originals or other releases.
Remakes themselves are also subject to the general wider trends of the industry as a whole at the time of release which people forget, which is why every remake from a Japanese developer in the last 5 years seems to be obsessed with adding bloom and very bright graphics (looking at you Bandai Namco and SEGA).
Take Sonic Colors. This game had a remaster recently called Ultimate which was subpar and had lots of issues. To the point where to community usually recommends a fan mod of the original game called Sonic Colors DX which runs a modified version of Colors in Dolphin.
I do get the argument that it increases accessibility and convenience, but imo it shouldve never got to the point where games need to be "fixed" by a rerelease nor should video games be tied to hardware either. more approaches like Xbox's backward compatibility and PC's constant game library are needed in the industry. I can download Sonic Generations right now from Steam, but I can't on another other consoles (apart from PS5 since I think they have it on PS Plus).
I think the idea that underpins it all for me is just the lack of creativity which creates a more stagnant industry as a whole. It's what's happening to Hollywood and it's what could slowly happen to video games if they're not careful.
Remakes where they translate games are fine but are few and far between, the only one I know of personally is Mr Driller Drill Land. Fan translation patches also exist for so many Japan only games that you'd be surpised!
Agree that we can just avoid remasters if we don't like them but at the same time they take resources away from new games
