Here's what I do. Your mileage may vary.
I have a Wells Fargo checking account and credit card. I use CASH for everything I can. I use the account very little.
The only things I pay with CC are the things I must, like my AT&T bill, and it gets paid with a transfer from the checking account.
For food, gas, property tax, auto repair, road repair, home improvement projects, contractors (when I was still building), I use cash.
The electric bill can be paid in cash in Sundance or over the counter at some local banks.
This balance works for me. I don't have to go crazy with alternative financial systems, yet all (nearly) my purchases and transactions are private. But different folks have different needs.
