Here was another thing that popped up in the discussion that I found interesting:
To that I would say, yes, but is destroying productivity actually a problem? I think the following quote from the Wikipedia page on "Basic income guarantee" is interesting:
...The connection between more and better has been broken; our needs for many products and services are already more than adequately met, and many of our as-yet-unsatisfied needs will be met not by producing more, but by producing differently, producing other things, or even producing less. This is especially true as regards our needs for air, water, space, silence, beauty, time and human contact...
I would not consider a 30% redistribution of BTC a "basic income guarantee" in the sense basic income guarantee is discussed elsewhere.
6M BTC are worth now no more than 40M$ (try selling 6M BTC)
30% that of are 12M$
per month that would be 1M $
How many are we? Are there numbers on MtGox accounts? 50k enthusiasts with some $ left to spend? That would be 1M/50k per capita and month. 20$ per month hardly is worth being called a basic income guarantee. For a Sri Lanka citizen things would be different though. He might open such a citizen account without putting $$ in. But through spending locally he would also solidify the currency in the overall economy. Taking our BTC would not be possible. As citizen accounts would need to also be subject to redistribution, the only way to profit would be by spending the coins. Accepting them would only make sense if the intention is to spend them again. A currency for paying, not for hoarding.
