> Land, however, is not built. Land is inelastic in supply, and landowners don’t “provide” land the way laborers provide labor and investors provide capital; they un-provide land by excluding others from using it. Building supply can change in response to a tax change, but land supply cannot.
But many cities actually can increase their land supply via land reclamation. This can be done by filling in waterways or otherwise altering the landscape to make it suitable to build on. Chicago, for example, built the land under the Adler Planetarium by filling in rubble along the shore of Lake Michigan. Boston is an even more impressive example; Back Bay used to be a bay of the Atlantic Ocean, not an entire neighborhood of a city with very high cost of living.
Cities can also lose land. Sometimes this is due to natural causes like erosion, sea level rise, or disasters like earthquakes and volcanic eruptions. Other times a lack of regulation might permit pollution to make land unlivable or infeasible to build on. Land owners can't create natural disasters, but they can advocate for policies that strongly influence effective land supply, such as whether building codes allow building on certain kinds or soil or require resistance to earthquakes.
Does this change the calculus from a Georgist economic perspective? If not, why?

You are confusing "location" and "dirt"
When georgists refer to land, they are referring to locations - not dirt.
Locations refer to the sections of physical 2D space that makes up a country. Why 2D when the world is 3D? Because parcels are allocated and segmented based on a 2D model.
Locations are best thought of as being similar to "spectrum" (what typically gets auctioned off every few years to the highest bidder) - there is a total fixed amount. Nobody made the physical space, and nobody will make more of it in the future. It all existed before life even began on this planet, and it will exist long after all of us are dead.
All that is true and I suppose there could be tax policies to encourage land reclamation, but this is more likely to run into environmental concerns. It’s literally an edge case.
The key is that land is accidental in a way - people don’t want “land” per se they want to DO something with the land - and if the valuations are high enough you get multiple uses.
The reality is that in the vast majority of places the valuations just aren’t there.

It isn't actually perfectly inelastic, but looking at land reclamation (and erosion!) relative to the ease with which places to live can be added to a locale, the supply of land is relatively inelastic. Even then, that kind of misses the core of George's argument about land value.
George himself distinguished land from labor and capital by looking at it through the lens of whether the economic value of a piece of land needed to be attributable entirely to improvements undertaken on that land. This is his "all natural opportunities or forces," and those are where the constraint lies.
For land reclamation in particular, there are two things to look at: (1) the value attributable to the land reclamation effort; and (2) the residual site value. (2) is land rent, and the Georgist model really is predicated on the relationship the surrounding community has with a piece of land. As it goes, if the community's feelings toward, say, a reclaimed waterfront are tepid, that reclaimed land won't have much value (even if the land reclamation were undertaken at great expense!), and won't command high land rents.
