Just because people might not fear their routers melting under large
network tables doesn't mean tomorrow they want 100,000 /30's in their
routing tables. The resistance is there so people who really positively
have no other choice - there are lots of other possibilities, and if
some unexpected sideeffect of lots of /30's pop up, the entire internet
suffers rather than just one customer.
