Communism occurs in part whenever a need is met or an economic decision is made without using value tokens. Direct access to resources without money happens every day (e.g. anyone using Linux rather than a proprietary OS, or exercising in a public park rather than a for-profit gym). The only thing keeping other products & services hoarded behind paywalls is devotion to capitalist ideology. It literally is a problem of capitalism. The structure of the world outside of people's brains has nothing to do with it.
