This may just be me, but I'd rather not watch something, than watch it with ads. Maybe if I'd been slowly trained to accept them, rather than backed into a corner by them until ad blockers and streaming came along, that wouldn't be the case. Once you live a life without ads though... I mean, virtually none at all... they start to grate on your nerves in a big way. I started to realize how much of my time was spent wasting critical thinking resources on dealing with marketing crap, and I wouldn't go back.
At best, people would capture streams with something like a DVR, then FF through the ads. Besides, with advertising comes advertisers, and their predictable responses to pressure groups compromising the actual product. Good luck making 'Game of Thrones' with ad money!
