How will this exactly kill the income tax? I understand what is being written, however the income tax is still due whether or not it is collected from the door or not. Not paying it will be considered tax evasion and that is not good.
Even if you do not pay your tax because you were using bitcoin that does not mean anymore that bitcoin could really eliminate tax(Government can surely review your assets especially if you leave in US or UK you are being monitored (just like what happened to coinbase that has a pending case because of not showing its customers records)
Nowadays, tax evasion is getting more and more difficult, for ordinary people. The government surveillance is getting stricter and stronger. Only the oligarchs and the billionaires are stashing their money in tax heavens now.
Well, it depends if to what certain place you are currently in. If you happens to leave in the first world countries especially in europe or United States then you are probably right but when you are on the other places in which government can't function properly then tax evation is as easy as hell especially if you are a small time earner.
