"Triflow the snooty man's WD40."
I'm willing to bet that the MAJORITY of new, geared bikes that are sold today in the US have freewheels. Removing one is a relatively routine task. In this case, "routine" isn't necessarily a synonym for "easy". Removing a freewheel can take a prodigious amount of torque. It comes off CCW. The only real trick is to keep the freewheel remover tool engaged while you're torqueing on it.
