Maybe you haven’t been convinced by a good enough argument. Maybe you just don’t want to admit you are wrong. Or maybe the chaos is the objective, but what are you knowingly on the wrong side of?
In my case: I don’t think any games are obliged to offer an easy mode. If developers want to tailor a specific experience, they don’t have to dilute it with easier or harder modes that aren’t actually interesting and/or anything more than poorly done numbers adjustments. BUT I also know that for the people that need and want them, it helps a LOT. But I can’t really accept making the game worse so that some people get to play it. They wouldn’t actually be playing the same game after all…
How does the existence of an option you never use degrade your experience?
For it to work well the developer has to change the game’s design to allow for the easier mode to work. If they don’t, it wouldn’t offer a good experience for neither the easy mode nor hard mode players.
The vast majority of games these days handle difficulty levels by simply tweaking the numbers of how much damage you take and deal. They build the game around a “recommended” difficulty and then add hard/easy modes after the fact by tweaking the stats.
Other games simply turn off the ability to die, or something along those lines.
In both of these cases the game is clearly built around the “normal” mode first. I’d be curious to see a clear cut example of that not being the case.
