I dont see how the public lands system can't be compared. If a company is willing to invest in a huge expesive mineral mine on free land, why not a any other company? If your company continues to serve the community and be productive, the company stays in business, much like now. If the company fails to produce, or violates the community's standards (or laws) they are out  much like now. 

This would just provide companies with less resources and money a more level playing field if they wanted to entry the market. Thus more up and coming small efficient companies.
