It's not sufficient to just lean heavily on cash. You also need to have a legitimate-looking explanation for where the cash came from if the tax authorities check up on you. Even if you can work anonymously and get paid via anonymously mailed envelopes of cash or Bitcoin, good luck living a normal middle class lifestyle while avoiding income taxes.
Buying a house or renting housing leaves a paper trail. So does renting or buying a car from most places that sell or rent cars. So does paying utility bills. So does paying for prescription drugs, medical services, car insurance, life insurance... So does paying for higher education.
I guess if you had some cash-only tax evading side business you could use cash to buy things like food, clothing, gasoline, and miscellaneous household goods. But you're not going to be able to dodge the taxes on middle class life's major expenses -- at least not without tripping the same mechanisms that catch drug dealers buying cars etc. with cash. I suppose you could live like an off-the-grid survivalist who never interacts with ordinary businesses. That looks like a lot more work than living an ordinary life where you work at jobs that don't involve trusting other criminals, buy things and pay taxes like usual.
