<a href="http://this.does.not.exist.com/index.html"> Link </a>

Have I not just created a link to something that does not exist?
Is this not quite acceptable in the current web architecture?

A citation of a book giving page number, paragraph and line number is
still a link, even if the book no longer exists. Not all links can be
traversed or dereferenced.

"Creating a link to" == referencing, in some cases quite optimistically

Thus your original sentence is not as trivially correct as you seem to 
believe it to be:

"For example, putting a URI up on a website does not "create a link to"
 a galaxy 100 million light-years away."

Does it "create a reference to" a galaxy?

Is this only a problem because it is a HTTP URI? Would it help if we
defined an urn:astro:galaxy-THX-1138 URI that could be used instead?

Seems like it might be easier at this point for the "web" to use URLs and
the "semantic web" to use URNs, but I'm sure that's been suggested a few
times before.
