Checks are not used anymore (excepting formal ones made out by banks themselves) because they are too easy to forge. And if someone write an unbacked check, you're out of luck. Banks don't back them if the money isn't there. I also don't understand why someone would prefer checks over cards because of 'hacking'. As if a scribbled note is som much more secure than a digitally signed transaction. Checks are outdated and while they might see anuptake again in contrarian US villages, I don't see it catching on in big cities where people don't know the one scribbling the piece of paper.
As for homesteading, I think many people have an image that is too romantic. It may work for low amounts of people, but it'll never catch on in big number.
