Clearly you need to play more civilization builder games. Grain is the most important asset, without it you can neither feed your people nor sell the excess to your starving neighbors for sweet gold coins.
I someone who hasn't bought a /new/ card since a 980ti, I find this talk of 'crypto burned gpus' to be a bunch of hooey. 1080ti x3, 1660ti x2, 2080ti x2... (We keep three gamers in cards around here, those aren't 'oh noes, this one fried, get another)... not one of them has had an issue.
Nor did the six P104s I picked up for an research project. And those cards smelled.. funny. I'm pretty sure they'd never seen aircon, and had no identifiable oem markings that I could find, but afaik, they're still chugging along 18 months after /whatever/ was done to them in their former life.
Honestly, I wonder if 'gpu burn' wasn't nvidia's first attempt to mitigate the cashflow drain of the crypto-cast-off-market.. before they decided it was more convenient to blame the need for drastic measures on a supply chain issue of their own design. -sigh-
