I'm sure spam directed at, say, enwiki, would get very subtle very quickly if spammers thought there was a real chance of it being able to use enwiki's pagerank weight. Don't underestimate spammers' ability to learn and adapt.
Also +1; pagerank is a valuable thing and Wikipedia has lots of it. Spammers would be quick to find ways to cheat, lie and manipulate their way into tapping into it.
Right now, we are plagued with the spammers that are too desperate or stupid to care; if we turned nofollow off, they would all descend upon us like a plague of locusts.
