anything that temped with money over here is a big offense
I think it all comes down to if the action threatens their power. A shooting at a mall is tragic, but doesn't threaten their power, so in the end they shrug their shoulders. Create a superior inflation-proof currency and they'll raid your vaults and lock you up - now that's a threat to their power.
I will like to know how these collectibles work
It's supply and demand - because only so many of these were made, there are only so many out there. They may have a very big "markup" making them more collectible.
