in the UBI version, the tax is purely redistributive. each of the 10 inhabitants pays some $ figure proportional to their monopoly use of the land, and then receive the sum divided by 10. if all inhabitants own roughly the same sqft, it has no real effect.

in the case where Georgist tax is used to fund public works, things look identical before outsiders move in. the inhabitants are taxed into some fund, and now receive payment from that fund for their charitable improvements. it’s a closed economy. however, once a non-charitable neighbor moves in, they too are taxed but do not receive anything from this communal fund (since they aren’t working to make communal improvements). now, the 10 original inhabitants continue to make those original public improvements they enjoyed making, and as a bonus, they all receive a little extra for their work.

depending on who you are, maybe you don’t like the idea of having “freeloaders” as neighbors, even if you’re materially better off for it. there are a few knobs you can tweak to shape the kind of neighbors you attract more explicitly (e.g. the $/hourly rate the community fund pays for labor, the rates associated with property taxes, etc). the key is that this tax is levied as part of a closed labor economy. you’re effectively monetizing the labor each neighbor was already investing into public spaces. the average neighbor sees no difference in their $ balance as before: no threat of not being able to afford to stay. UBI does better at protecting the elderly, community improvement fund better at protecting the hard-working/able-bodied.
