I should have phrased it better, indeed what I meant is self hosting by "declouding" from public clouds. My only concern is realiable self hosted backups. But I already have my own setup for newsfeeds, document storage, even for calling friends and relatives, and at the fraction of the cost (I factor in the value of my privacy as part of overall cost). I think there is good potential for self hosted products out there. A major pain point though is self hosting emails, since that requires a lot of work around spam protection and availability.
