I also see no reason to let anyone, the government included, know where I go, what I do, and what I buy on an everyday basis.
I don't even have one of those grocery store cards that you get money off of your purchase. Why?
Because I don't want anyone, the government included, to know what I buy.
I’m not one who places a high value on professional psychiatric counseling....but in this case I think that you need to see someone about your irrational fear of leaving a “paper trail” for mundane items.
I figure...let them track my purchases at the grocery store or a couple of bucks for a danish and coffee. Take $20 or $40 in cash back from the debit and save it for the purchase of firearms and ammunition with cash. You go to the back and withdraw $700 in cash or write a check to Jimmy’s Gun Shop then they have you anyway.
All my purchases go on a credit card, which is paid off at the end of the month. I've never incurred any interest charges, I actually get to float someone else's money for ~30 days, and I get Hilton Honor points for every dollar spent (which adds up to six nights in a premium Hilton resort about once every two years).
