Bitcoin was created to liberate us from corrupt governments and corporations that serve their own needs. The coinbase transaction in the genesis block, mined by Satoshi Nakamoto contained: "The Times 03/Jan/2009 Chancellor on brink of second bailout for bank". What is your opinion on paying taxes on Bitcoin? The government most likely doesn't know my bitcoin address. Even if they do find it, based on the transactions made from my bank account to exchanges, I could simply say someone stole the private key from me. Many of the posts here asking for help on filing taxes on their Bitcoin make no sense to me. We have a system that allows complete financial freedom and yet people choose to pay their taxes from it and support crooked governments.
Saying that likely won't help you as you will have to prove it one way or another that the key was actually stolen. That would be a whole story worthy of a separate thread in Legal. Now to your point. People pay taxes not because they are willing to do so (while some are but they are in absolute minority and beyond the scope of this post). They simply don't have choice. Yes, they can choose not pay taxes but then they are exposing themselves to the risk of being caught for tax evasion, and in some countries, that may mean a term in jail and severe punitive penalties (the US and Canada seem to be most atrocious in this regard)
In other words, people prefer not to mess with the IRS (an abstract and exemplary Internal Revenue Service)
