I think article is arguing that localhost still has cost when onboarding and maintenance cost that is not really that visible because maintenance happen while devs are doing other task - but usually it is included in some task to setup some config. So I would agree localhost can be basically free, only that company has to keep developers in-house and not burn through 10 juniors each quarter. If company wants to burn through people like Amazon in warehouses then having cloud dev-env is way to go.
