Yes, ultimately it's the way peertube will likely be if we want reliable servers that stick around. Paid for accounts for those that want to upload. The way I figured it was both a server with 1-2TB of space on a server and/or 1-2TB of S3 space is the kind of money I can forget about. But much more than that, and I can't afford to be hosting other people's stuff like that for free.
