GC claimed that food is all that is needed, and that their wants were satisfied by the additional of the other two things.

The fact is that the average human is not actually content to be one notch above animal with "food, sex, and purpose". That is why we have progressed much further than just accepting those basics as all we need. But I think our improvements on those things do provide enough value for the average person to be happy.

- Tasty food

- Safe sex (and relative ease of reproduction)

- Multi-variate / chosen purpose.

Plus other methods to remove annoying friction from your life:

- Optimized shelter

- Optimized travel

- Consumption of various raw goods (not for food and not for shelter). e.g. 3D Printers!
