Using pricing to mitigate abuse is only necessary if you're not doing anything else to mitigate it. Imagine a collection of independent storage pools managed by various entities that control access, e.g. the IT guy of your family, your employer, some free software collective, some small business association. You join one (or more than one) based on a referral or personal relationship or whatever criteria they want to use. Then you have an account with a quota in excess of what any ordinary person is going to require but which doesn't allow Bob to dump 500TB of garbage into the pool without first negotiating with the administrators. At which point the altruistic donations, i.e. the idle capacity of the devices of everyone in the pool, are enough to handle everybody's non-abusive workloads.
