So, why would any country be communist?

In this one, I'm offering an alternative perspective on the thing I'm critiquing.<br><br>Communism is unrealistic because:<br>Human beings have two primary needs: survival (hunger/shelter need) and mating (sex). <br><br>So, why would anyone choose to live in an economic system that doesn't need money, and thus doesn't reward people for giving their labor? <br><br>The only logical communist system I can think of is a virtual one, and only in a post-scarcity economy (where AI produces all goods with no need for man). But an in-person communist system is not logical, because one simply cannot satisfy their sex need with communism, especially given everyone has the same thing. If money doesn't matter, one has nothing to buy for sex and no one would ever get sex, even if everyone was granted a house. Everyone would just starve and die with no sex, so one would want to live in a capitalist system and have money. <br><br>What's the communist's argument in response to this and what's the need for money should everyone in a communist society get a home and no one has to work? <br><br>Thanks.
