I think he wants to stay out of the system 100% to achieve a tax free life. So far is he is doing great, since the first step is getting paid of BTC and buying with BTC, without interaction with fiat whatsoever.
I don't think that is why he did it.After all he still need to pay tax unless he's living in a country( or a citizen of a country) that have zero tax.
A lot of what he is doing is going to allow him to avoid the reporting requirements that would make it easy for a taxing authority to know how much income the OP has.
While I do think it would be a bad idea, it would be possible for the OP to hide a good amount of his trading income, especially if he properly maintains his privacy
