All large format printers have appreciable non-upfront costs.
I try and emphasise this in my more general print related writing - personally I take it as just part of the cost of being able to make large format prints. It would be simpler if these costs were more transparent (that applies to all manufacturers) but they currently are what they are.
Without knowing Epson or Canon's engineering design criteria, I don't feel I could describe any aspect of their design decisions as 'stupid'. I might find some (such as the page length limit in the PRO-1000) curious, or unduly influenced by the dead hand of marketing, but modern inkjet printers are rather fine machines.
I've long felt that if the extra costs of heads/wasted ink make that much of a difference to someone, then they need to re-evaluate their business model.
For those of us that don't print that often, I prefer to think of owning and running a large format printer as not dissimilar to running a classic car ;-)
Let's just suppose that some here aren't even operating a business, just a serious, expensive hobby, to start. But, if you insist on addressing the small business owners in the photography and limited edition printmaking field (because, high volume printmakers see little issues with reliability issues, and costs can be written off somewhat) then consider the low margin competitive climate of that world, and rethink that comment. They aren't driving Porsches, sir.
And classic car is quite a generic term. I mean, Triumphs were hard to keep running when they were new, but some old Chevy muscle cars just keep on rumbling, with minimal attention.
