Doing the best imitation of myself
Simply put, this notion does not follow at all.If it is not a problem for some of us, it means it doesn't really need to be a problem for anyone. Unlike your example, the only resource you need is a resourceful GM.
I dare to think that most GMs are able to plan ahead for resource management issues and, with a slight change of perspective, manage to keep the PCs in the game for more than one encounter a game day. Not saying that every game day needs more than one encounter, of course.
To me it seems that part of the problem might be the expectation of the players that their PCs will get rest after each and every encounter. Once you let that happen, you may have a harder time weaning them off it again, but it is either that or stop complaining about what is a matter of GMing and player cooperation.
For certain types of playstyle, and certain players, this is not an issue. What if you as a GM don't want to run that kind of game, or what if your players don't see eye to eye? A game system that runs a narrow set of games well is not going to bring in as many players or GMs as one that's more inclusive.
Saying "just run it this way, and players: just play like this!" is, well, it's a solution, but it's not one that's going to get me to run or play in that kind of game.
