I don't think so. Bandcamp, specifically, only really keeps tabs on your purchases (ostensibly something you're okay with, since that's the point), your shipping/billing information (saving this is optional), your name (no obligation to be real), and your email (mine's an alias).
Ultimately, these sorts of things are all trade-offs we decide for ourselves, but by creating an account, you have an additional layer of protection against losing purchased music, as well as opening the ability to stream your purchases (I don't use this feature regularly, but found it useful once during a power outage when the nas hosting my music was down for a couple days).
