It's the government trying to enforce their opinion of who should own those Bitcoins, thereby taking power away from the owner that the network has decided on, which would be "whoever has the cryptographic keys".
We can, and should discuss subjects without "tainting" them with general, over-discussed points when we can, especially if we want to keep HN curious and not turn into a echo-chamber.
At some point we need to stop wasting oxygen on obvious garbage.
If this domain received 1/1000th as much attention and electricity I would be with you. But until then we could do with far less waste.
Definitely not a compelling reason.
On a side note, Islam requires a 2.5% Zakat from money hoarded in your account, to be donated to charity, so there's your solution against hoarding :) We don't need the government to fake print money to prevent people from hoarding. Better that money go into charity to truly have a more equitable society, as opposed to the fake and useless proposals we keep seeing and pitting parties against each other.
