that's what money flow should look like.
community (town, city) donates money to people, who then use it to buy goods and services from companies (which make a profit that way) that are then taxed by the community.

If the company makes a profit, and doesn't pay employees, then you end up with a perpetual extraction to the benefit of the company owners. As to services/infra, it's a policy choice where what those are, but still require funds to provide them.
UBI works conceptually as a baseline income and with the continual squeezing of workers out by automation and new technologies may well be needed, but if there are no employees paid to runa company or government workers to enact these policies then things come to a halt.
