Yes, but what kind of comfort will dominate people when all types of 'butt-comfort' are satisfied?
This correlates with my previous quesiton. What good will be in private property when ALL your needs can be satisfied here and now. Will private property be so important to you? Even if it will - well, you can get a ton of gold and put a sign 'Private property' on it. Other people will just think you're a weirdo of sorts and pass you by.
They won't ENVY you and envy is the primary driving force for the desire to posess things.
Let me answer this question for you - they try to sell me a car because they want my money to buy them something else (maybe even also a car). Capitalism states that you are better if you posess more and consume more. But think - does a greater level of consumption really make you better?
What? Maseratis are not good? (shoked) How that may be? They cost so much money! They must be good!
Your difficulties with communism lie not in the theory, but in the sad 'practice' you wintessed back in USSR. USSR had its faults, and many of them, but this doesn't automatically mean that the theory itself is bad.
