You could live in a shelter and rely on donated food and clothing.

You could also avoid income taxes if your income is below the threshold.

You could avoid the gas tax if you don't have a need to buy gas.

You could avoid the cigarette tax by not purchasing cigarettes.

So, still think that taxes must be unavoidable? The reality is that even if we personally do not pay the tax, others do, and that factors in to the prices we pay for goods and services.
