People who want to live under Communism
Rather that expecting everyone in a country to live under communist rule, people who want to live in a communist society should start a commune of their own.
In such a commune they can share possessions and take care of each other economically.
This is a vast improvement over the imposition of communism on a whole country by the use of force, as happened in Russia and China last century, leaving millions dead.
Imposing an economic system on people through force is both immoral and ineffective.
People will perform much better if they get to choose what type of society they get to live in.
Otherwise it gives rise to rebellions and attempts to sabotage and destroy the system from within.
So for those who are happy living in a society with property laws they can continue to do so, while communists get to form their own communes with like-minded people.
