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.

I believe the grandparent just means free access to birth control. Ie “With our current technology the default state doesn’t have to be pregnancy anymore.” It’s phrased a bit weirdly, I’ll grant you.

Reproduction is one consequence of one specific sex act.

Hetero vaginal intercourse often doesn't result in procreation, and that's your best shot at it anyway.

There isn't really any universal default consequence, just like there isn't a universal sex act. A lot of people enjoy it, some people feel shame, etc. Life is a spectrum.

I'm not the one who made the statement.
