Look at New Zealand and countless other countries who have forcably unbundled their networks. Everyone pays less and there is true competition between providers.
Utilities like the internet gravitate toward monopolies and less competition. Utilities MUST have regulation to protect consumers from their monopolistic nature.
At least as to wired Internet, they don't: https://www.akamai.com/fr/fr/multimedia/documents/state-of-t... see also: https://www.recode.net/2017/12/13/16773062/global-internet-s.... The U.S. beats Germany, the U.K., France, Spain, and Italy (the countries comprising the large majority of the EU population).
The U.S. is also one of just five countries to have more than 90% LTE coverage: https://opensignal.com/reports/2018/02/state-of-lte. The big EU countries have faster LTE speeds, but much lower coverage (ranging from 65% in Germany to 83% in Spain).
Belgium has a 94.5% coverage as per last year. The report shows 85%.
The reason is pretty simple, per the report: "OpenSignal's availability metric tracks the proportion of time users have access to a particular network."
That's not coverage. Your source doesn't show what you think it does!
To be clear, I am not talking about safety regulation, but competition regulation.
