If you completely ignore the cost of routing table growth to give
every company their own PI, sure.

Reasonable is a hard word. We've had to turn away customers who
wanted to assign a /27 to each and every machine, without actual
justification for more than 3 IPs per machine. Sometimes people want
to do insane things that aren't technically reasonable, but it's what
they want to do. NAT gives them that option.
