Is too much weight put on trading....??

I noticed that on easier difficulty levels < normal I was able to pretty much get away with not trading with other civs. On normal difficluty and above, it seems that you MUST trade or all the other civs will come at you-- good or evil. Other than extra income from the trade revenue why does it seem that you HAVE to trade or set up lots of trade routes? Do the computer players treat this as hositle so that they come at you eventually (nearly all at once )? Have any of you won at the higher levels w/o trading?
So yes I would consider trading really important, and it´s important to renew your old trade routes with more lucrative ones later in the game.
What I do though is watch that STATS page and the MISC tab, when a race is 1 to 2 weeks away from completion of a tech I already have, you might as well trade it or sell it to them, it gives you income/influence and it also increase your relationship with that race. The key to this strategy is you MUST stay ahead in the tech race at all costs. So, keep that research slider up there pretty high 50% or better.
