You're deliberately misinterpreting what he's saying. Apply that 'logic' to the first clause: Dying of disease or predation alone in a jungle or on a savanah is the default consequence of living. That's biological fact. You can't legislate that away.

I know why you picked that latter bit - it makes a cool sound bite. But it's just wrong, and whatever 'biology' imposes on us, we as a society shouldn't look at those loose shackles and say, "yes, this is the way it must always be."

ALSO, reproduction is the default consequence of a specific kind of sex under certain conditions, it's not like it's a 100% guarantee. Treating it as such makes you sound like a Texas lawmaker's favorite textbook.
