In my opinion, the answer comes down to this...
If you want to play 5E in a particular setting bad enough... you'll put in the work to do so. Just like if you want to be a Dungeon Master at all at a level you yourself are comfortable with and proud of... you'll put in the work to do so.
And if you don't have that desire bad enough, you won't. Which is completely fine. You either keep playing the game version that requires only a more minimal amount of work that you're willing to give it, or you play in a setting you might not like as much, but which again you can do so with a more minimal amount of work on your part. Both of those answers are absolutely okay.
And in the mean time, if you want to express your dismay on the EN World boards, that's cool too. Your only payment for doing so is possibly reading a bunch of other people coming into the thread to give you "suggestions" to solve your issue, or tell you your desires aren't going to be met any time soon and to deal with it. Which ALSO is absolutely okay, because that's the reason for having a message board in the first place.
You have to choose what is most important to you... whether that's playing a particular setting, or just expressing your disappointment on the internet. And both expect a payment from you-- either your time and energy for the former, or a bunch of people unwilling to make you feel better about your disappointment in the latter.
And that's the eternal struggle for a player who has certain desires about how to play D&D the way they want.
