I agree with most this... but have somewhat of a counter point to "you can't copy a page title".

You (often) can copy a page title into a client (Google) and expect it to find the right resource. This is usually done with articles, etc.

Even your comment provides a perfect example - you didn't link to RFC 1736, but the text "Locators are human transcribable" is unique enough that the first Google result is correct.

So you didn't have to provide a URL to lead someone to this page, just 'enough' unique text for it to be findable.

Which is kind of amazing - and maybe not what the original RFC intended.
