The problem with YT premium is that they simply do not have content worth paying for. Even the very best content (say, videos where people give music lessons) is not actually something I would pay for. I don't mind paying for a streaming service - I pay for Netflix and will for the foreseeable future. But that's because Netflix has stuff where I actively want to watch it and would miss it if it was gone; YT does not.
Depends on your perspective I guess, personally I find YT far more valuable than any streaming platform. University lectures from hundreds of professors, conference recordings, music videos, millions of independent creators covering nearly any niche you could think of - YouTube's service of hosting that and making it available is worth so much more to me than whatever shows Neflix currently has on rotation.
But since I have the option to not pay, I don't. If it was paywalled I'd be willing to pay probably 3-5x what a normal streaming service charges though.
University professors are already (often publicly) funded and should be sharing videos on university infrastructure, not ad-funded commercial platforms.
