For some people, this may represent a barrier to hosting their own f= ull node.=C2=A0=C2=A0 After all, if you have to pay $15 just to get a copy = of the blockchain, that just adds to the already expensive prospect of host= ing a full node.=C2=A0=C2=A0

In the long term, this should cause stable nodes to stick aro= und longer.=C2=A0=C2=A0 It also discourages "installation spam" a= ttacks on the network.

Fees for other node operations can= be considered if this is successful.
