Yeah. Except, we've gotten rid of those large bills we used to have - which included the $5k bill.

Cash is terribly inconvenient to the powers that be. In addition to the irritating ability for me to transfer value to other people or companies without an overt trace, it puts a reasonable lower bound on the effective interest rate - you can't go much below 0% without people just paying to hold cash. It's not relevant right now, but a few years back, the noises about how awesome negative interest rates would be to properly stimulate demand were rather loud. There are a few books written as cover fire for this concept as well. If you put $1000 in your bank account today and will have $995 next year, may as well spend it to stimulate the consumer economy instead of "hoarding" it, right?
