Not prior art. You don't need patents to establish prior art. Just
publish your idea and you're done. (The problem with just publishing an
idea is that someone might have a patent application regarding a similar
idea and might modify their application to cover yours once they see it.
Later, when you go claim that you have prior art, there will be a heavy
burden of presumption on you. This, of course, encourages you to apply
for a patent...)

Patents let you have counter-suit options should you get sued for patent
infringement -- that's the "defensive" in defensive patents. You need a
large portfolio of patents, and this doesn't work against patent trolls.

There's also no-lawsuit covenants in grants. You get to use my patent
if you don't sue me for using yours, and if you sue me then my grants to
you are revoked.
