Valuable chart in terms of protecting your UTXOs. In the past when massive amounts of dust transactions have belonged to a single entity they have worked with miners to run large consolidation transactions that would otherwise not make it into the mempool. 

 Very true, I worry though that in the future of blockchain that cost will be very exorbitant, and won't be available to a pleb. 

 As transaction fees rise, hopefully, Lightning ⚡ give us some viable options. It needs development and then adoption, but it is  making good progress.
