I don't know why you have these kinds of thoughts. you may even have bad experiences related to those things. Well, I will give my thought also here, but only on some points:
Don’t pay taxes
Taxes from the government in a country is a must and there will be some punishment if we do not pay for taxes. Well, as you say, we may be rich if we do not pay for taxes, ut, our life will not be calm and we must be chased by the authorized party and get punishment. Personally, I will prefer to pay for taxes and live well and calmly without worrying about the problems.
Don’t get married
Are you kidding me? Have you got married? Did you divorce or experience a bad marriage? I don't think that this is a wise decision to be rich. As you know, my life becomes better and better, my income becomes more than 3 times increasing after getting married and after having a child. You should know that marriage can open your other income, having child will also open other income. Why? because you will have our responsibility to always work harder and harder, you get supports from your beloved family, and also you are not alone to struggle. And those are awesome. After marriage, we will also be able to control and manage our finances better.
Don’t use bank
yeah, it may be true, moreover never loan for banks. I agree with this because loans from banks sometimes will make us stressed and it will take our money more. However, unfortunately, personally, I still cannot leave banks.
After reading your statement, I don't know what's in your mind. I think that it will be better also for you not to eat because eating means spending money.
