Do they have your information? (I assume they do.) You'll likely get a bill.

This is an interesting concept but I can't think of a single truly unique quality that each human has that couldn't be faked. Fingerprints change, DNA is easily acquired, and recognition software can be tricked. Information is the only thing I can think of.

I get what you are saying but sometimes you just pay a premium for convenience. Laptops can do some things that desktops can't. I don't regret paying a lot for my Asus ROG because it is 4.5 old and still running like a well oiled machine. Sure I could have bought a desktop but I wouldn't have been able to game in a lecture hall or on the bus.
