Interesting thesis.
The issue here is that the instrument market has bifurcated along socioeconomic fault lines... the difficulty for stores is in the aspirational crossover between economic classes, where a musician might aspire to own a Fodera, want to try one, but absolutely cannot afford one on their musician's income.
This is partly the fault of the manufacturers, who sell their instruments as gig-worthy holy grail instruments for elite musicians, but then price them so high that only an orthodontist or lawyer can afford them. This isn't to impugn the legal profession (they do that on their own and don't need my help), but it's a disconnect between what's being advertised and the reality of what's being sold. Even if they manage to get the scratch together, no working musician who plays bars and schleps their own gear is going to take an instrument that cost as much as a car to a gig that pays the band only a few hundred dollars. The risk of damage or theft are too great, versus the paltry reward.
So, bringing this full circle - is the store at fault for not stocking these instruments? Absolutely not. No lawyer is going to buy the musical equivalent of a Bentley that's been dinged up by Joe Schmo Off the Street with a stagnant income and moths in his wallet. And Victor Wooten isn't going to Guitar Centre for his basses either - he'll receive his parcels directly from Fodera. Let's be honest here as well: social mobility hasn't been a thing in the US since Reaganomics. So, the odds that the aspiring Fodera owner will ever actually make the purchase is vanishingly small too, regardless of the false ideal of the "self-made man".
So, why would a store stock instruments that only the economically deluded will ever play, will get beaten to hell, and will never sell, except at a steep discount? Unless there's a strong correlation between people walking through the door to see a Fodera and walking out with a Squire or Fender, there's simply no business case to have it.
