Yeah, this is a risk.
The best approach is to take advantage of the fact that Bandcamp lets you download everything and simply download everything you buy and keep backups (as you would with any other important data)

Even if there aren't labels requiring artists to hide or delete music from Bandcamp, you never know if Bandcamp could just go down one day for financial reasons and then you're screwed.
Beets doesn't maange handle the extra files that the zip often includes, such as PDFs of linear notes, the sheet music I once found included, or band photos. Maybe someday I'll figure out a good archive for everything that isn't "the literal zip file".
