Keeping the fruit of your labor should be called saving, not hoarding.
LOL. Inflation is force, currency is force, but let me guess - property rights aren't a form of force right?
Sorry, but bringing the use of force into this is the first sign I'm talking to a libertarian, and one that is not open to any form of reason.
Hoarding the primary means of exchange (what BTC advocates would really like BTC to become) is a negative for society. As the hoarding increases so does the value of the item, encouraging more hoarding and less lending and concentrating wealth in the hands of those that already have it. Not really a recipe for a healthy economy.
I'm not advocating what you personally, or society should or should not do. I am simply pointing out that some people have gold and others want to take it away from them. My question is: what moral principle makes it valid for some people ("government") and makes it invalid for others ("thieves")? If the principle is "some voters voted some people via secret voting", then Hitler did nothing bad. Also, if the principle is "decision of majority" is moral, then more questions arise: on which territory do you define this majority? How can morality flip completely when 1 extra person joins another camp or gets to a legal voting age? Etc.
If you want to redistribute gold, it's up to you to show why it is justified to kick someone in a face because of "hoarding". And when you start explaining this, it will be you who comes up with some definition of property rights (maybe by saying "hoarded gold does not belong to you, but to society").
Also your Godwin (democratic taxation = Hitler) is just hilarious.
