A lot more jackass than the blockchain spam is the mass acumulation and hoarding of first bits.
You know, in my country domain names are free to register, and we got the same kind of greedy people running crazy bots and the such to be able to register as much as possible. Thankfully they later had to and were able to cap it on a per person basis, but the damage was already done. We will not even be that lucky here. These abuses will ran rampart.
"Hey, here is a free amazing resource BTC has which, incidentally, is great for newbies, usability and further adoption."
"Oh cool. IMPERIALIST MODE ON. Let me capture them all before anyone finds out, and then sell for 20 a pop out of thin air."
Nothing further from the ideals of BTC and precisely the opposite of what we need right now IMHO, but I can't however negate the fact that a free market is a free market after all.
