Filecoin miners can do the same by (a) registering as service providers and (b) complying with blacklists and takedown notices as mandated by their legal jurisdiction. Note: Filecoin miners don't just store arbitrary files assigned by the network; they sign contracts with specific clients to store specific files. The only difference from Amazon is that the network itself enforces these contracts.
No, the difference is that Amazon's contacts can identify the buyer and they're actual, legal contacts. They also have terms and conditions. Miners have contacts in terms of what the network is doing, which have nothing to do with contracts as understood by law. These are two meanings which just happen to use the same word.
That would be a huge overhead to be replicated across participants, driving out smaller players, lowering the "distributed" aspect of the system, creating larger points of failure and increasing the price.
