Wouldn't the solution be for nodes to use whatever mechanism an attacker
uses to determine less commonly available blocks and choose to store a
random percentage of them as well as their deterministic random set?

IE X blocks end of chain (spv bootstrap), Y% deterministic random set,  Z%
patch/fill set to deter attacks


Then he uses Sybil attacks to obscure what's actually rare and not. Even
proof of storage isn't enough, you need proof of INDEPENDENT storage, which
is essentially impossible, as well as a way of determining which nodes are
run by the same people (all the AWS nodes should essentially count as one).
