And equally, I don't disagree with anything you said either.
But I would point out that - assuming they are doing this with the purpose of getting a serious music project "to the next level" and not just hobbying around - for the price of a typical entry-level 8-channel home studio they could easily rent all the studio and engineer time they needed for the whole process from tracking to mastering, and not have to make any sacrificial choices at all.
But if one wanted to be completely honest, what's really happening is that the average home recordist is led to believe by manufacturer marketing and Interbull that making "next level" recordings is easy and that it is indeed just a matter of having an LDC or two and a plug or three, and it's not until it's too late that they find out that's simply not the case, and wind up depending upon you guys to bail them out. I don't begrudge you this, we're on the same side here, but you guys are certainly not hurting because of this - or at least not as much as those who work in the earlier phases of production.
Though now you do have the added evil of trying to distance yourself from the hacks out there who call themselves "mastering services" because they have a copy of Blowzone and too much free time on their hands. I don't envy that part of it.
