I was being overly pedantic, yeah.
What I was getting at is that there's still a way to play retro games using original hardware. It's not impossible, and using original hardware can be fun for its own merits.
But yeah, "not available anywhere else" can be implied to mean "for sale by the rights owners" and that's fair.
