Not too sure it really is as close to solving the debate and I'm not sure either of the guys backing Modern Money Theory or Austrian School theory (this
link in case anyone wants in) would agree this lays their case(s) to rest!
Oh, I am pretty sure most of them will disagree. They also disagree about Bitcoin having value... What this paper does is bring actual scientists into the debate rather than leave it to social theorists.
Interesting read, nevertheless. But there's also a lot of fresh conflicting evidence against the selfish gene (@dothebeats for e.g. more evidence shows we're not as instinctively anti-altruist as we think, as a recent Swedish study of public CCTV footage shows), suggesting that modern generations using modern money might actually not fit the logical mould anymore.
Have you read the paper? It says that cooperation is not the same thing as altruism. That is, it rejects the selfish gene paradigm (as a lot of biologists are doing recently).
Guys, it seems to me that everything happens and happens much easier and there is no need to appeal to high matter, as speculators manipulate the cryptocurrency market today, and Fiat is supported by states, because their economy depends on it.
