What will happen if someone moves the coins of the mentioned reused addresses that do contain thousands of bitcoin? A lot! I would not try it.
Theft is theft, you can sugar coat it however you like but it is stealing someone else's money. Not to mention that from a cryptography point of view if a single P2PK output could be stolen, all bitcoins outputs are in danger regardless of their type because there is a short step from there to speeding up the process that lets anyone steal the coins in a transaction while it waits to be confirmed. That makes bitcoin obsolete overnight.
With your argumentation, governments could say this:
Money printing is money printing and is a criminal act. What the Bitcoin community is doing, is money printing, or money creation, or money issuance. You can sugar coat it however you like but it is stealing government's money and distributing that money without the permission of the government.Governments allowed Satoshi to 'print' Bitcoin.
Satoshi will allow 'whoever is able to do it' to transfer these coins.
Governments will allow it.
Yes, you don't believe it. Then we have to wait until it happens.
