The difference between “use” and “purpose” is semantics. Did you think that when government seized property in order to lay down the Transcontinental Railroad, the land did not ultimately go to private entities? When they seized land for utilities, do you think there weren’t private-owned utilities that ended up as owners?
the words have different meanings. from cambridge.
Purpose: noun: The reason for which something is done or created or for which something exists: the purpose of the meeting is to appoint a trustee the building is no longer needed for its original purpose
Use: noun: The action of using something or the state of being used for some purpose: a member of staff is present when the pool is in use theater owners were charging too much for the use of their venues
Railroads have a unique history in the US. but i do not believe that eminent domain can be used to transfer ownership from a citizen to another citizen. if it is taken by eminent domain is is available to be used by everyone. easements should be negotiable by the persons involved in the establishment of the easement. most utilities started out as private and worked thru the basic property rights associated. Gas companies ran pipes under streets etc because the streets had been taken by cities. Just beacuse it was done doesn’t make it right or constitutional.
