Are there even that many businesses that only let you pay via PayPal? I don't think I've ever encountered one. I use PayPal often enough for convenience (and to avoid giving out my CC number for a one-off purchase from a new website), but I don't think I'd be too bothered if I had to close my PayPal account. And yeah, if I ran into a website that only accepted PayPal, and didn't have an account, I'd just move on and buy somewhere else.
