Let’s revisit that once SAFE is out.
At the moment SAFE is not out yet, so it’s less meaningful to compare something that’s available now vs. something that isn’t (if you say SAFE is available, fine, but then you can use the same opportunity to compare plausible deniability and anonymity features of the current SAFE MVP vs. ZeroNet).
Tor is certainly slowish (I get 50-200 KB, which is probably enough for video streaming, but it wouldn’t scale if everyone tried to do it). However personally I am not interested in high-bandwidth apps and (see below) most users probably aren’t either.
Of course that would be valuable… when it becomes available.
In the meantime take a look at OpenParasite.co - there’s a bunch of Torrent streaming sites already and outside of the US people can watch them with impunity. And it’s “free” (of course it’s not really, you get ads and maybe malware with the movies/music, but 90% of people don’t give two craps about that).
ZeroNet and Popcorn are free, which means the price is unbeatable. The only reason Popcorn users might want to use SAFE is privacy, but that is a concern mostly for US based users. In the rest of the world you can watch anything in your browser, without installing any software.
ZeroNet + Tor is fine for low bandwidth, private and public content such as forums, blogging and so on, and it works today.
SAFE can be better for some other things, like high bandwidth apps and reliable content repositories, archiving, etc.
There’s no reason why people wouldn’t use the both.
