There's a big gap between asking for support for alternate playstyles to assuming they're incompetent.
I've found that 5e works really well if I run it like I used to run 2nd Ed, but it is deeply dissatisfying when I try to run Eberron. A big part of that is conflicting style choices - 5e assumes items are not easily for sale, and Eberron assumes that there are. That doesn't mean either set of assumptions is wrong, it just means that they don't work together.
Since I like 5e and I also like Eberron, I'd like to see them play well together, and a reasonably well-constructed set of item prices is a big part of that. I'm willing to wait, but my interim solution is "don't try to run Eberron in 5e", which is far from ideal.
That's why it matters.
This comes down to a setting support issue.
It is also a lot of work to try to run Dark Sun or many other settings.
