I personally don't have 200+ tabs, so I can't speak to this problem, but I don't think you are going to make much inroads telling people to change how they work. So rather focusing on hypotheticals, I'm glad that Mighty provides a solution that doesn't require much friction or behavior change.
Why is $5 an acceptable price? Why not $10, $50, $500?
Edit: You agree that having 200+ tabs is a problem right? Why haven't the people with 200+ tabs adopted the solutions you speak of? Perhaps those solutions aren't good enough, or perhaps they don't want to change the way they work. Either way, if those solutions really "solved" the problem, we wouldn't be observing people with 200+ tabs in the world.
