Crypto = Fiat?

This is the first time I've ever attempted to write anything. I don't have a lot of skill at writing, so I'm sorry if this doesn't make sense.

I'm just starting to learn about crypto currencies ( bitcoin, ether, etc) and have lot of questions about them. So hopefully I will get people to respond and explain the concept to me. Along with any idea's and feelings about the subject. All points of view. The more different opinions and ideas I get from people the better it will help me understand.

Personally I love cash. In my work I get a paycheck, but 98% of my income is cash. ( and I just made up that sat, but it's definitely a large portion) my job is not a sexy job. But I have a good schedule, flexibility and I get paid mostly in cash. I like that because I don't declare that income. Therefore that is less that is stolen from me. I believe tax is theft. And nearly ever purchase I make and income I earn someone is stealing from me. Be it the federal government, the state government or the local government where I live. I'm sure all that money is going to building roads and education like I'm told. And not towards the interest the federal reserve charged for making money out of nothing. But that is getting off subject.

What I'm most interested in is getting out of this scam we call the federal reserve. I'd like to have some way of exchange that could bypass them and the government stealing my economic labor. Why should someone who creates nothing or provides no service. At least services I don't want and didn't ask for have to power to take mine. But that is something I want to learn more about. Is there ways to not be tracked? What good would it do if the government can track my transactions? Eventually they'll want to make laws to tax those also. I got a Coinbase wallet. But it asked a lot of personal information. So I got a Jaxx wallet and transferred what I had to that hoping it is more private.

I also don't know how I feel about crypto for the reason that I don't like the thought of a cashless world. But as a supplement I would think that crypto would be good. I know this is not complete or perfect it's just trying to get some of my thoughts and questions out there.
