Of course, natives got away with them, because the national park service, park rangers, paper, pencils, ink pens, carbon and ncr paper, civilization, hadn't been invented.
With invention, round stones, axles, modernity, society improved....

unless you are a sanctioned, licensed concessionaire,
in which case you can let things run down to a natural, more primitive state... .. .
