I wish we could do away with physical money altogether. Go to a 100% electronic currency and forget about it. Other than for haircuts (as my barber is cash only) I haven't touched a physical dollar bill in three years. There's simply no need for it. Going 100% electronic would have many benefits including, I believe overall less crime. Since everything would be logged and there’d be a paper trail people would think twice if they choose to purchase illegal stuff. And if they go ahead and do it anyway, guess what, you’re busted. Plus I don’t see the friendly neighborhood crack dealer accepting Visa and MasterCard anytime soon. With no physical currency illegal activities like drug dealing, illegal weapons distribution, prostitution, illegal gambling, under the table jobs and all the like would take a big hit and we’d all be better off.
