(a) After conferring the privileges of this subchapter upon any person, no county court shall again have power to confer the same or like privileges upon any other person to the injury of him or her upon whom the privileges were first conferred.
(b) However, privileges or franchises shall not be exclusive and effective against any county, counties, or the state. All privileges or franchises granted hereunder shall be subject to the rights of the county, counties, or the state to condemn them and acquire the property and franchise by condemnation proceedings which shall be exercised under the right of eminent domain as the same is now exercised by railroad, telegraph, and telephone companies.
