You can. In fact, it already is so long as you renounce the use of political power--government force--and seek only voluntary consent from others. See my answer to “Can you start a purely communist society in the US?” The answer is yes, any time you want. Think of the hippie communes in America, or the Israeli Kibbutz. They are examples of voluntary communism. Americans have never had a problem with such arrangements. It is the imposition of communism by force and violence on people who don’t want it--Marxism--that will never be feasible (acceptable) in our society. So, go ahead. Start your communism. Just leave government out of it. Any other method is the method of a gangster.
