I too have seen far more than one group do it, often with a dramatic sigh and rolling of the eyes as the group piles on agreeing with the course of action. Perhaps your own experience with players outside your personal social group of players is not as broad as you think & could stand to be widened before deciding with such certainty what "anyone" would doNo, the "we will sit and do nothing for 24 hors just to rest" is stupid and I refuse to believe anyone would do that. If this is an issue, stop playing with weirdos who do this.
And really, if you have players give you up to 32 hours, while they sit idle...well, a lot can happen in that time. Baddies get reinforcemens, emptied rooms get refilled, traps get reset, ritual goes off snd now you have Cthulhu to deal with on top of the boss, or villain summon backu/bodyguards. Stop running static world that waits for pcs.
In short rest you regain only hp equal to roll of you used up hit dice +Con modifier. You only get half of the used hit dice on long rest. Regaining hp through short rest is diminishing returns.
I don't even know what is the point if last paragraph, could you explain it in a way that doesn't look like an angry rant directe more at yourself than person you are speaking to?
It was not uncommon for GM's to simply declare that there were no more of those wands for sale right now or that some of the critical components required to craft them were out of stock/season due to overconsumptionCase in point, the 3e cure light wound wand.
Playing 3e without access to that wand (or some equivalent of it) is a NIGHT AND DAY different experience.
Going beyond that, I reject the idea that healing consumables started with 3.x and would further add that by needing to heal all lost hit points without being able to wish damage out into the cornfield via death save yoyo healing made those charges too precious to fritter away recklessly in actual play. The ad&d2e DMG has a line that read something like "healing potions should be readily available" while suggesting 200gp.
