This sounds awfully theological to me.
>You cannot flatten a society when inequality is the fabric of evolutionary forces, in essence subduing the genius workaholics to the same levels of award as the troglodytes.
I honestly have no idea where you get this idea from, and I've had to explain it so many times; it's a popular misconception about Communism but I simply have trouble understanding where it originates. If you don't mind me asking, where did you get this idea from? As far as I know, no Communist espouses it. For a counter to your point, take a look at Kropotkin's Mutual Aid: A Factor in Evolution[0] however your very premise is flawed; Communism does not mean the absolute equality of everyone, as even a child can see that people are different and have different strengths. Communism is merely a more equal system in which people receive the product of their labour in fully.
> To ignore the universe, filled with lesson upon lesson that all life is in constant competition to survive
This is a tired point, the fact that it is still trotted out reeks of naturalistic fallacy, and the idea that humans are no better than the universe, ignoring the fact that the forms of oppressive have changed but the relationships remain roughly the same. You seem to suggest that capitalism, or at least some class society, is necessary. I see no reason to believe this is true. You assume that these systems are natural, deriving right from the universe itself; again, you expound theology.
>that life feeds on life
This is a funny point because even though this is unavoidable, humans have created ways to minimise the extent to which this occurs, by consuming less life i.e vegetarianism. Do you see how this thinking can also apply to, say, capitalism? We may not eliminate certain pressures but we can certainly reduce them.
>build a society that does the opposite is to invite an end to all hope of prolonged interplanetary existence
Not really. I'd say that capitalism does this instead, and the reason is that within capitalism we could only hope to do that if it brings profit to the speculators. This idea that capitalism is a promoter of human progress is obviously false given the great amount of pollution, false science etc. which happens in the name of capital itself. If we can't even care for this planet, what makes you think that capitalism nurtures prolonged interplanetary existence? The very idea seems ridiculous to me.
In short, you've confused nature with a rather recent mode of production (which optimises for things that aren't natural at all) and used a theological argument to say that it must be this way or we'll be doomed to massive turmoil and never leaving planet Earth.
