I would assume the consumer that always wants thing cheap cheap cheap, the fact that consumer printers were more or less designed and build in someones garage all come into play.

I should contact https://filamentinnovations.com/ after covid and see if they give tours since they are only a couple hours drive from me. $15,000 USD for 18.5"x15"x36" build area allows you to print larger than life objects easily.
