Agreed. My reply follows similar thinking as you.

I disagree with your assessment. The Guidestones weren’t there to help society rebuild after an apocalypse. It was built to scare you into thinking an unavoidable, likely human caused, cataclysm was coming. The builders clearly infused “bad human” into it’s message when they say to keep the population under 500 Million. It’s all part of the narrative to keep people chasing the cheese at all expenses. This creates ample opportunities for someone else to get rich off your fear. It’s similar to the gold rush. Who got rich in the gold rush? The merchants.

Yes, tax them to the bone.
