Blockchain has better uses than just currency. Imagine holding all your own records on blockchain. Land deeds, vehicle deeds, birth certificates, marriage contracts, business contracts bank records, all of it. Not the local or federal government. Then if you need proof of date or time you have a forensically accurate proof. If the government wants a record they can get a warrant and PAY you for the record. They wouldnt be able to access it unless you gave ot to them. All patents held private on blockchain. If you could prove you were first a court would find for you. The ultimate in 4th amendment security in your papers.
