I wouldn't necessarily trust others with my data, but if a person wants to trust themselves then that's up to them.

Symmetrical high speed connections allows for the option of self-hosting one's own stuff and being able to serve it to the Internet (or connect to it remotely), but it is not mandatory for people to choose that option. They may not feel confident in their owns skills so choose the option of paying someone else to be responsible for it.

I'm simply talking about having more options.
