Now who's being simplistic...
Life doen not simply come into existence in all it's complexity; there must some driving force for it to extend beyond the most simple stages. In our case, evolution got us to where we are now, and curiosity is driving us where evolution can't take us anymore. I cannot imagine life just staying put; it must either advance or go extinct.
1) All life considers itself supreme in apparent absence of the contrary. The vastness of space will also ensure at least millennia of breating room between first radio contact and first real contact. Besides, if they are capable of interstellar traval and willing to destroy us at first sight, what are the chances we have escaped their attention for so long?
2) Wars will be fought before resources become so scarce we can't power the LHC anymore. If they couldn't spare any resources to begin with, they wouldn't have advances as far as they did.
3) Yes, and somehow all of them will have missed electromagnetic radiation and its uses entirely.
4) Just like us, they son't know, but it can't hurt to try.
5) Intelligent hyve minds don't just suddenly dome into existence, like our beloved Gods.
6) This is just a temporary redistribution of resources.
And so on.
Fermi's paradox is a paradox, a discrepancy between what we see, and what we would expect to see, in essence telling us to look for other ways of communication besides messages in bottles.
In conclusion, we are not special, and it is very likely that our development is simply the most likely one. Our environment, in all its abundance, is simply the most likely one to spawn life. We are not special, and therefore every other civilization will probably be a lot like ours.
