I like that approach in theory, and especially for dramatic shows.  There’s a million American shows that could learn a thing or two with that, tell your story exactly how it should be told, and get out. 

But for comedy, do you really think that there wasn’t a single other funny scenario they could have set up at Fawlty Towers (just an example) before they moved on? I feel like if everyone’s enjoying it and the setup isn’t tired yet, there’s no reason to just stop doing good comedy for the sake of stopping, at least when actually good comedy seems to be so hard to find.

Of course not. Problem is we have multitudes of real life evidence showing (my opinion but I feel it's a popular one among neutrals) that American tv shows get ran into the ground and become terrible, whereas British ones finish early and stand the test of time. I don't think comedy is any different. Just look at the Simpsons compared to mr.bean. More loved than Mr. Bean in it's day now it's shockingly terrible. I said that the Simpsons is my favorite show to a group of teenagers once and they couldn't believe it because in their own words it was 'so bad' and 'not funny'. It's a shame that such a great comedy had to go out like that but unfortunately that's the way Americans do TV.
