> Taxing real estate at large causes a supply-side pressure, driving up market prices.

Not if you tax the value of ground rent only. If anything, the effect goes the other way, as owners are incented to put their underused properties on the market. (And yes, taxing ground rent only in some relative small areas e.g. around a station may introduce distortionary incentives. But in general, shifting taxation towards land improves the incentive for good government, especially provision of local amenities.)
