I don't think there are as many .410's as 12 ga. to start with. The .410 is attractive because of low recoil and usefulness where a lighter charge is all that is necessary. On the other hand, guys like me buy them for the "romance". A good old Cooey .410 has appeal. I have a neat little Mossberg .410 bolt. I have two old SMLE's in .410, one 3" and one for whatever length the .303 British cartridge is. I also have a single shot of some kind, not sure of the brand. Plus they are neat little shells. All kinds of good solid reasons - romance, neat, attractive, and more!!
