Pregnancy and childbirth are physically taxing for women. Most people of reproductive age want sexual relationships. Many people want children. Very few women want to give birth to 12+ kids. Even the wives of billionaires don't have that many children, despite having more than enough material resources to support them. (Elon Musk's 12+ children required several women.)
Replace dozens of kids with any piece of wanton consumption then. How is it checked? Hoping we get bored of orgies and parties and feasting and this is enough to ensure we can reproduce indefinitely and continue to orgy and party and feast? I don't think so. At the end of the day, the world cannot sustain everyone living with the carbon footprint of a wealthy person living life to excess. It can't even sustain the carbon footprint of everyone living how they currently live.
Our bodies do that naturally. I can only eat 5 or 6 before I'm too full to continue
The amount of projection in this post is truly staggering. You do realize there are parts of the Earth that aren't the Bay area right. Also, those feasts require a shockingly large staff you normally don't see to make them happen. Finally, most of your complaints aren't even true. The amount of farmland has shrunk over the last 100 years by a large amount. The amount of forests has expanded, by several times. The fisheries are the one thing you are actually right about and that's because a couple of countries (mostly in Asia) are speedrunning fishing. Seriously??? this is your take???
I am not sure most do.
