Regardless of how you are understanding "workplace democracy", no conflict occurs between the public controlling land usage and the public controlling enterprise.

Georgism simply advocates that lands would be rented from the public by private entities, some of which may be private enterprise or rented housing. The general understanding is that private profits would be partially recovered by the public to compensate for private use of land. It expresses no support for the abolition of profit.

If the public controlled enterprise and housing, then it would of course control land usage. There is no particularly clear case for any problem in leftist tendencies being solved by Georgism.
