I don't know. I'm not familiar with Georgism. It's called "erfpacht" in Dutch, and it's an old practice. Amsterdam is the only city I'm aware of that does it on this scale, but it's not unheard of elsewhere.
Google translation of the Dutch wikipedia page for "erfpacht" [1] translates it as "Ground lease" and suggests it is used in various countries including the Netherlands, about which there's a large section. I don't know how well the translation is w/r/t technical terms, but it reads ok to me.
Is this like ground rent in the UK for leasehold property? This is a thing but usually a fairly insignificant cost as long as you keep renewing it with decades to spare.
UK ground rent goes to the private owner of the land though, which is mostly not the state. That's why there was a scandal recently when some landowners tried to impose a ground rent that doubled every X years - which the government has thankfully banned now.
