I fully agree.
I have yet to see a single person recognize such a social cost to their GMing, other than the banal "you won't have players."
Which, as I've said, no GM lacks for players in this digital world. The GM shortage is eternal and intense. One might say it's a seller's market.
Traditionally, this is a self-correcting problem.
Back in the old days (
finds beard to stroke) ... the way a lot of games evolved was organic. People would play and learn how to play. Over time, one of the players would start to think to themself, "Self, I think I could run a better game. In fact, I'd like to try it!"
And then that player would take their ideas and become ... a DM. Usually, it would be rough sledding for a little while- because it's a lot easier to point out mistakes than ... you know, to actually run a game.* But they'd get the hang of it, find their own voice, and run games! And then, one of their players would start to feel that itch...
So it goes. As you correctly note- it is a seller's market. Because it's a lot easier, less time-consuming, and less stressful to play than to DM. It's certainly easier to focus your ire on a single point than to worry about how to make a campaign appealing to a disparate set of players so that everyone, not just a single player, is having fun.
Despite this, we see that there are many players who demand that their preferences are catered to. To that I will say only the following- I hope you find all the gaming joy that you seek. But the only way to have a game run the exact way you want it to be run is to run it yourself. Instead of criticizing all the terrible DMs out there, become the great DM that you demand others be! Be a positive influence. Put all of the material you've learned into practice, so that you can teach a new generation of players how to "play the right way" according to you, and you can also show them how to "DM the right way" by example, so that when they go off and DM on their own, they will have learned by your example.
Be the change you want to see.
