True, but there's an important distinction. The early church was VOLUNTARY -- nobody was forced to join it. And even more importantly, it was ALL CHRISTIAN, so there were no serious value disputes, as to how to allocate resources. To share all property and money with another person (as in marriage) or with a group of persons (as in a commune), is a form of "yoking" -- your destinies are linked. The Bible tells us it's wrong to intentionally become unequally yoked.

State sponsored communism is totally different from early church communism - it is NOT voluntary, the state forces you into it, and it is NOT equally yoked, in fact it's a case of mass, forced unequal yoking. Even in democratic socialism, forced unequal yoking can occur, for example: if you have a socialized medicine plan, covering both Christians and nonbelievers, the taxes of Christians are being used for abortion, euthanasia, etc. This wouldn't happen in an all Christian commune.
