I think the paper is mostly referring to what governments

I know... Notice that I'm further asking "how easy it is...to
But yes, my question was ambiguous. By "what can be achieved"
I'm asking : how effective the traffic analysis

True of course, so 'easy' becomes even easier...

Something any ordinary proxy can do most of the time. Even
ISPs/the 'interweb' by their own nature hide 'ordinary' users
from each other.

That seems somewhat odd given the tens of thousands of millions
of stolen money 'allocated' to 'research' every year.

That may be so. In that case we are not talking about
'beliefs' but about actual knowledge.
