It's different, but similar. We do actually care about other property ownership -- we tax various parts of its production to encourage the outcomes we want. That might be taxing based on country of origin, of materials used, of cost to dispose of, etc.

But land is intrinsically tied to housing and food production. We should be strongly discouraging allowing usable land to lie dormant because someone wants to speculate on it. Land should be taxed in a way that encourages maximizing housing/business/service utilization. A city block dedicated to surface parking provides almost no utility compared to placing a forty story mixed use residential building on the same lot. Even worse are property speculators who purchase abandoned sites and do nothing with them for years in hopes that property values will rise considerably in an urban core.
