People actually emulate a ton of games not available on virtual console. In fact, emulation is a pretty popular way for people to play fan translations of games that were never released in english (tales of phantasia, radical dreamers, etc.).
It's true that there are plenty of folks who pirate chrono trigger via emulation but there are also plenty who want to play the more obscure titles out there.
I am aware, but I noted a defensibility for those cases, didn't I? I am, however, skeptical of any claim (not that you are making one, but such a claim in general) that they are a majority, or even significant minority, of the set of people who download and use emulators.
