Another way to look at it would be; what if you owned your own 152, kept it at an uncontrolled field, and had the funds to put gas in it for as much as you wanted to fly. You could fly all day every day as long as you could afford the gas. There would be no real way to verify this, but it would certainly be legitimate. I'm sure there have been plenty of guys buy an airplane to build flight time, and there was no "paper trail" other than their pilot logbook.
