Totally get you on this. My own tastes are pretty caveman when it comes to guitars: I've tried but didn't cared for locking trems and active pups and such. Thing is, I gave them a go and decided they weren't for me. Aesthetically, I like my guitars to look like they could have been made prior to 1962, but even then I find the market very limited and closed minded - especially as a left handed player. (It's incredible how often some idiot these days still trots out the old lie about "guitar isn't handed", "you should find it easier with your dominant hand on the board" and such). Even within my own tastes, which do have their limits, I find the market narrow. I'm sick to the back teeth of hearing about "tonewood", or dogma that "guitarists should always buy the best [best meaning most expensive] they can afford." The worst I remember was when the first Variax was released, guys all over Harmony Central falling all over themselves to be the 3,009th say "Enjoy your toy" in sneering condescension. Even those who said they'd try one if they put fake pickups on it and made it look like a "real" guitar....
Honestly, I know Leo Fender had a time of it back in the fifties, but if he had to deal with selling something innovative to today's market, I don't know how he'd cope.
Probably the one that drives me up the wall most is the abject refusal by so many to try something other than tubes - I've even seen many flat out reject the idea of even trying non-tube where it was guaranteed to sound exactly the same, simply because of, as you say, this misplaced notion of authenticity. The absolute worst are these fifteen year old kids who sound like their grandparents haughtily announcing "there's no good much like Led Zeppelin being made any more." You're bloody fifteen!!! Find your own thing, you have the time!!! MARLOWE ANGRY! MARLOWE SMASH! RAAAAHHHHHH! Ironically, I'm going to end up with tubes myself for no better reason than I can find a small, simple Champalike much cheaper than anything else I've looked at, but I always have an eye out for the price coming down on those Roland BluesCubes, or a chance to try one of those Session Blues Babies that claims to make SS sound like tube. If that works at the right price, I'll dump the tubes in a heartbeat. I'm already perfectly happy with SS for bass.
I always have a laugh when some brand-snobs criticise the like of Tokai for not doing "something new", then when they do see something new (even from Tokai)....
