You can tell boomer hands wrote this. I am neither in favor or against a cashless society, but being able to stick money in birthday cards is hardly important. Personally, I find cash to be a pain in the ass to deal with because you have to take it to the bank in person to deposit. I get the argument that without it you would be vulnerable if the government decides to freeze your assets or something but if that is your concern then cash is probably the worst defense against it. Visa gift cards achieve the same purpose if you need emergency spending money and aren't any more traceable since you don't generally have to register them and if you are saving a lot of money out of a bank you are better off buying an asset that increases in value like silver or gold. I honestly can't think of a single important thing that can only be done with cash or even one that is easier to do with cash.
