You're not the owner of your data if you farm out storage/serving of that data or transmit it with weak/no encryption. You could pay someone to store and manage your data, and have contracts with them to prevent them from sharing the data. But you better be sure that data is stored at the 3rd party encrypted where you hold the keys, otherwise those contracts are meaningless to the government who can demand access to your data in secret if they choose. The way forward I can see is for us all to host servers run from one's own home and with replicas stored at trusted friend's and family's houses in case of disaster. New protocols would need to be invented to replace things like email though, it would require quite an upheaval.
