The Internet just seems really specific (see the list of others at http://www.un.org/en/documents/udhr/).
That's why people who campaign for positive rights make a grave error, IMO. It cheapens the entire concept.
That's roughly what taxes are for, yes.
> Why is the Internet a human right but electricity, which is kind of critical to running the Internet, is not?
There are a number of arguments for electricity being a human right. I'm perfectly okay with saying it is one.
That said, the interesting point is that you're imagining electricity here to be an implicit right of Internet access. That's fine, but it implies that, if Internet access did not require electricity (and who knows, maybe it won't someday), the claim is that Internet access remains a human right without a need to imply a right to electricity.
Freedom to access internet is to same level, it means human people shouldn't be arbitrarily blocked from accessing internet, that's all, that's enough, and that's already a lot, actually.
You seem to be asking this rhetorically, but I don't see what your objection to people being allowed to demand access to the Internet is. Could you actually spell it out?
