I think you're misinterpreting the argument here.
The cost of entry to the game is the same for every potential player, no one is asking for extra money to get "in touch" with anything. Money isn't buying yourself easy access to Sekiro, only skill. It is the individual player skill that creates the issue of accessibility. Thus it is the creator's individual desire for what game they're making that is at stake. Not everyone is entitled to a modified creative intent just so they can consume a product. To assume you, as a consumer, should have a right to satisfaction from every product, and that a creator must make everything digestible by all potential consumers is most certainly a very capitalist perspective. Clearly someone discussed "should we make something that EVERYONE can spend $$ on and get something out of" was weighed against "do we really care about more $$ or making what we want to make", which has been stated by fromsoft on multiple occasions in the past. They make what they want to make regardless if it'll be a huge profit generator or not.
Ambiguous films don't come with explainers for those who really don't have the critical tools to unpack them, or the lack of desire to unpack them, but we aren't making threads about "are complicated plots bad because they're inaccessible".
I just want to be clear here, i am not trying to deride anyone for their skill level. And if Sekiro had an "easy mode DLC", i'd say your argument had more weight. But that's not the reality of the situation, we're discussing the issue of creative intent vs consumer satisfaction. And if you're not satisfied as a consumer and feel you have a "right" to satisfaction because you're willing to spend money you're part of the problem as far as watering down of creative intent is concerned.
Also at the risk of making an "elitist" argument... I don't think any soulsborne game is really that hard. Sekiro is probably the easiest one, and bloodborne the hardest simply because in sekiro, blocking is obscenely strong and easily exploited to make the game easier. I really personally believe people just really don't want to learn to not play it like a soulsborne game. 9/10 you can win a fight by barely moving if you just learn the rhythm of block, attack, occasionally jump or mikiri. You don't even need to be good at blocking, you can just mash the block button and win the game. It's far more forgiving than it is given credit for.
