I think it’s not a coincidence that land value tax is popular on Hacker News. Replacing all the taxes that tech companies currently pay with a land value tax that hardly affects them would be an incredible boon.

It's an incredible boon to the vast majority of society. The only ones who suffer under LVT are land speculators and landlords.

Their servers exist somewhere, and while it's called The Cloud™, that ain't literal ;)

Datacenters, offices, warehouses, factories... these all sit on top of land. Even a fully-remote company running off Raspberry Pis in someone's closet still requires some quantity of land on which the employees' homes and that closet full of Raspberry Pis sit. Even if the companies themselves don't own that land directly, somebody does.
