“Mr. Yenor is director of state coalitions at the Claremont Institute’s Center for the American Way of Life. Ms. Miller is director of the Center for American Education at Idaho Freedom Foundation. They are authors of a report on Florida’s K-12 system.”
This is conservative propaganda
My opinion, from a similar situation, use the coax to pull cat6 through and replace it. Assuming it’s not stapled down or too tight. In a previous home I rented I didn’t want to run cable knowing I would only be there a few years so I picked up MOCA boxes; lets you run eth over coax. I connected a switch in the bedroom for a steam box and smart TV to the router downstairs using this and worked fairly well but never did intensive bandwidth tests. Might be worth looking at.
