I recently printed from the DFA70-200, resolution is so high, I could sell the photos for advertising on the walls of railway stations and airports. That's pro grade. I guess, the apsc and limited lenses would still well suit the amateur photog, and the K1 and DFA* lenses would well serve professional use. A lot of people nowadays use their mobile phone, the results are not as excellent as with a DSLR, but for many , a carbon copy is enough. Reading some technical discussion in the posts of this forum , hints that the community is very much into the details of images, where the general public could not care less, except when you show a print and everyone wants to have it without knowing why

You seen advertising on airport and railstations for quite some time but 36 or 50MP FF wiht modern design lenses are quite new. They are by no mean necessary.
We had report from pro shooting for 3mx4m advertisment too... They explain the actual image are not that big, because it doesn't matter.
And you'll find pro working with all range of gear. Remember that:
What make the photo great isn't the gear. We buy expensive gear because it is the easy part.
So sure you can buy whatever you want/need no issue with that. Some still use chamber and film and scan, because it beat all the rest hand down for sharpness, details and there the interresting rendering. Some guy shoot the olympics with it even one could think the AF isn't that great.
One can take the biggest/heavier/most expensive lens, this is just a few clicks away to buy. There no issue.
But this doesn't change much. It just that you know for sure if the picture isn't great it can be the gear as you have the best out there, but that's it.
Knowing that, what make sense is to buy gear with an interresting set of compromize. You said it yourself, you go for f/2.8 zooms on FF because you think you really don't need more on such format. So you get conveniance, great quality without having to bother with few extremely expensive primes.
For some it will be get a few small/light prime that provide all the quality you need, keep the overall bag small and benefit that even with a DSLR, if you have a small lens people don't notice. You are unobstrusive.
For some, what count the most is to have the best gear so if there something bigger/heavier/more expensive and with more extreme characteristics, it's for them. That were the manufacturers lead us, as well as reviewers because it what make them money. And as consumer, it is the worst situation to be in because it is the most expensive where you always need more. But ok, that another way to experience it. And as long as you can pay for it, there no issue. That or something else...
