I know people who would abuse this and make full use of the services while never contributing anything towards it. That goes against my sense of fairness.

I'd prefer a pay-to-play model where people pay a fee to the community for the land they own. Landlords and overseas 'investors' (parasites would be a better term) who collect rent from people in the community or leave plots of land vacant while they wait for capital gains to accrue wouldn't get a free ride anymore.
