Why is stalling considered so bad in chess?

Hello there, i was thinking a but recently, why is stalling the game in losing position considered bad?

I mean the main point of chess after all is to win a game. I usually play lower time controls since i don't have time to play 30 min game, but when someone stalls the game in losing position, i respect that, not gonna lie. 

If you got yourself into situation where you are in losing position - parking ticket, let's say jail time, etc, you would do the best you can to win, even if winning seems hopeless, resigning or accepting loss if all your options are not exhausted seems stupid

If you get into situation where you are very close to losing, isn't stalling just trying to use your own time to win?

You can either move and lose, or let your opponent wait for however long you have left and you might get a win?

You understand, it's your own time and your opponent is not forced to wait for you, he can resign or pffer a draw if he doesn't want to wait

I'm not stalling myself, since i play mostly blitz, but i thought about it and in retrospective i consider my opponents that stalled smart

What do you guys think about this?

I can certainly see this perspective, but when the required patience greatly outweighs the reward, stalling is considered disrespectful.

Imagine you're playing a pro soccer match and you're winning 7 - 0. You're opponents sub out players every chance they get, but you start to notice that they're subbing in and out the exact same players (assuming you get more than 3 subs). You know they're just stalling for an inevitable loss, so I ask you: is stalling smart?
Honestly, (imo) stalling is just a cheap tactic to hope that you can outwait your opponent and secure a win you didn't really deserve.

I understand your point , but it is a but different, in soccer match you would inevitably lose, even if they had to wait 30 minutes

But in chess match, if your opponent resigns or leaves, you will take the win

I get your perspective as well, but i don't think that following rules would result in disrespectful win, in the end it's the win nontheless, you know

Every politician when he has some drama creates distractions to stall for as much time as possible for people to forget

Or rich people using money to stall justice system, so the other person runs out of money or can't continue

Would you say their methods are stupid or smart?

It's the same as their, you are no longer thinking and might be doing other things, so you are not even wasting your own time, you know
