Anarcho-communism (and similar ideologies) isn't really about everyone being equal, that's a silly goal that would take enforcement and calculations, it's not practical. Instead, anarcho-communism is a different way of living based on cooperation rather than exploitation and doing what is needed for people rather than what a few rich owners want.
You and a "lazy" person won't necessarily have the same outcome. A person unwilling to even pick up after themselves or contribute would still be guaranteed housing, food, and health care, but that's about it. You on the other hand could work to have a nicer place or acquire things, so long as you aren't getting them exploiting others or common resources. If you build a nice chair the anarcho-fuzz isn't gonna come and take it to split it amongst the community.
The thinking around "laziness" needs to change. A person unwilling to do even the absolute minimum might be called lazy, but A person unwilling to trade their time for money isn't a bad thing. It's not the "lazy" people that wipe out species, start wars, and cause climate change.
