I would've agreed with you if I didn't start with Firefox on my web design journey. I never found scroll bars to that problematic because FF has pretty sleek ones. So I always ensured scrolling worked on overflow, when I started to more seriously test and use chrome I was absolutely disgusted by those vile thick scroll bars that would ruin my amateur design. But by that time I had understood that scroll bars are a need not a want.
They are a want. You can keep scrolling functionality without having scrollbars. If you write apps that serve the biggest demographic possible I get your sentiment. I dont want to serve to the biggest demographic possible, I want to serve specific people.
