Is co-operation at odds with consensus?

Let me try to outline this.

One anon coin with a 1,000,000 daily volume is BETTER than 5 anon coins with aggregate volume of 1,000,000 (200K each). One anon coin in litecoins position of not being seriously challenged by a like coin - hence holders are not in danger of losing their capital will attract more investment and move towards establishing a defacto anonymity coin. Having 5 anonymity coins constantly trading places between spot 5 & spot 13 on the market cap is less valuable as a whole than having one winner that is not seriously threatened.

One currency will get anon crypto much wider adoption than five.

I am unable to understand the "together we are stronger than apart" (I also have very little use for shilldom.)

But I don't understand this "We can all co-exist and it will be better than having one"

Someone explain?
