Communism has had no lack of second chances.

There's no law against forming a commune in the US. Lots of groups have. Feel free to found your own. The problem with communes in the US, however, is you cannot make anyone join or stay.

Accomplishing that requires a government, and has been tried lots of times, most recently in Venezuela.

Given the historical results of government imposed communism, I'll pass on giving it another chance.
