You're correct, but I think capital may still be distinguished by the degree of value added by labor. Ownership of land and natural resources is a different form of capital than ownership of shares in an company or a factory building, but both would be considered "capital" broadly. I think the distinction is in how much labor and human ingenuity has been added to create that capital.
People should own what they create (organizations, buildings, goods, and services), but the natural geography of the world should belong to all. If one wishes to lay claim to a stretch of land, and prevent all other equally born humans from entering or making use of that land and its resources, one should pay a tax to society for that privilege.
As you say, "people competing to allocate capital for higher returns" is a great thing. However, I dispute the fact that some people should even have the right to decide how to invest their land without first paying a societal price for it (much higher than current land tax levels--high enough to cover a corresponding decrease in most other taxes on labor or production).
