Are you suggesting that the burden should be on channel owners to upload variations of their videos that don't include sponsor blocks? That's a bit onerous. My commercial agreement is with YouTube, not with the video creator.
If you don't like ads from creators, don't watch those channels?
YT Premium does provide the "skip ahead" functionality that almost always jumps over sponsor blocks.
I will say I've been a YT Premium subscriber for years and I've never seen any ads for other Google services in my feed, and I don't get advert emails either.
