I understand where you're coming from but I think your analogy proves my point, not yours.
If someone steals your gold, you definitely should ask for legal assistance I agree with that. However, the executive order 6102 is the historical moment where the US government decided that you are no longer allowed to hoard gold and should use their notes instead. (https://en.wikipedia.org/wiki/Executive_Order_6102)
This shows that governments have the power to "steal" your money legally! They can give you a note instead of a currency - again, legally! - and then years later sell the gold and leave you with worthless notes. That is stealing, but it is technically agreed by the majority since in a democracy there are elections.
In your analogy, the witnesses are the government, and they are elected by stakeholders (or the people in a democracy). Since the witnesses can pass and execute laws on the blockchain by changing the code, and since they have the approval of the majority (they are elected), why can't they steal your money legally? They can, and did so in the steem case, and with the support of the majority of the voting stake.
In a company, there is a shareholder agreement protected by law and therefore the government that majority shareholders cannot simply decide to vote to steal someone else's shares. However, in a DPoS blockchain, there is no shareholder agreement or contract protected by the state. The only rules are those in the code, and everyone who bought the coin knows this before buying the coin.
If you want to define what the witnesses/Justin did as stealing, I accept that in a conversation, but not in legal terms. I also believe they stole, and went again important principles that they should have respected, BUT they definitely did not break any rules or laws. They simply used the DPoS system, which we all agreed to be a part of.
I would insult Justin Sun gladly, but I wouldn't sue him.
