Pragmatically, the reason I would want municipal broadband is because it would be less expensive than Comcast or whatever private provider, right? But would it

Pragmatically, the reason I would want municipal broadband is because it would be less expensive than Comcast or whatever private provider, right? But would it be? I've used various of the major cable internet providers over the years and I can always get all the speed I want for $80 per month or less. Or is this mostly about internet access for the poor, tax-funded?
