You were mentioning that FF is not more expensive. Third party alternatives are always cheaper (regardless if they're better or not) than brands' lenses. This is why I mentioned Nikon vs Fuji. Now, I agree that in Fuji's case that's really a shame they don't open their mount info to more third parties (like Sigma).
But regardless, overall, APS-C is much cheaper than FF.

As far as limited lens choice it totally depends on your point of view and use.
For me, it's the exact opposite as you: Fuji is the least limited system at the moment. For my use case, no FF or other system beats it in terms of lens selection (whether ML or not, regardless of sensor size).
