None of those things are necessities for life. To survive, to be alive, I do not need to use on-line vendors.
Here in the Netherlands we increasingly need to... Various government taxes already can only, be handled online. Currently the taxes that can only be handled online are those for all (small and large) businesses. And if those businesses refuse they are put out of business. Individuals can still get a paper form for their income tax but it's already strongly discouraged. More and more parts of the government are going an online-mostly or only route, not only for additional stuff but the essentials.
Many businesses stopped sending bills through 'snail' mail. Most communication businesses (telephone, cable and internet providers) were the first to do so. Banks are decreasing their number of offices throughout the country rapidly. Most of the time only the major cities still have one (1) office where you can do your banking business. (Such an office would have to serve ten of thousands of customers if not a majority was doing his/ber banking online.) For the rest they only offer online services. The least expensive health-insurers (with the basic package) only offer you service if they can send bills electronically and medicine can only be ordered through an internet-apothecary (after you get a prescription by a certified GP or specialist of course).
With other things, not interacting online causes a hefty financial penalty. Getting your receipts through mail is a value-added option, not included in the basic packages for those businesses still offering it that don't have to send you the actual goods by mail (like shops... which are cheaper most of the time, by the way, if you order the goods online). The best deals on contracts for electricity, cooking gas, all insurances, savings accounts, mortgages and other financial products, communication products, etc. are found online.
If you want to access the educational system, you have to be online, if only it was to sign up for an actual school or university (for college education or equivalents or better).
A person in the Netherlands which doesn't have access to the internet has either a very poor standard of living or a very high one (because he can afford to opt-out).
I would say, here in the Netherlands the ability to have an internet connection capable of doing all this described above is a right. Of course that does not imply you should get a connection for free. You should still pay a proper (but also limited) fee for your connection if you decide to use the services of a provider that provides you with said internet connection. The providers however are (and increasingly so) regulated, for example, by means of laws for things like net-neutrality and the anti-telecoms-monopoly agency OPTA. And there are also government subsidies for providers willing to implement connections to places less profitable. Which is all fair, considering you can't really live in the Netherlands without having an internet connection of some sorts.
