I think the key difference between the services and living life with "Pre-Internet" substitutes is that all of the services have been designed and engineered to elicit a certain usage.
When you use something that was designed, there's a certain set of axioms governing that thing. You've got to buy into someone else's interpretation of value. If you're aware that the other person's interpretation is different from your own, then you'll be much more likely to have the self-control needed to interpret its value for yourself. The danger is that most people don't do that and as a result fall prey to their own assumptions based on what they were told is valuable.
The trickle of pre-internet information doesn't compare to the firehose we have today. There's not one single solution and I agree that a governance of these ethical ideals will be tricky no matter what form it takes.
