Not sure if sarcasm or flame bait.

I don't think it's either? Internet outages are relatively common. I wouldn't want my pacemaker or ventilator to just stop working if there is an internet outage for example. So I agree with them, for anything important(or rather extremely high availability) you don't depend on the internet.

I was curious if any aspect of local hospitals, required the internet to validate licenses, for example.

I wouldn't be surprised if stupidly, something important did.
