I've never heard of any well-known economist arguing labor and capital are the same; got any reference?
I'm not sure why you ask me for a reference for a claim I didn't make. I claimed that labor and capital are substitutes as inputs to production. I also claimed that an inferior or more expensive substitute may go unused when a better alternative becomes available.

Do you disagree with any of these claims?
