I don't understand why everything we do in society has to rely on capitalist concepts. The internet has shown that we can have a system that works without the usual capitalist market concepts that are somewhat needed in the "real world". Via decentralized applications, we're seeing that we can build services that are not powered by hungry corporations which sponsor segregation, unethical behaviors, inequalities, competition and destruction. Instead they're powered by the people that use them.
