Bring back the thing where you slip in money in a shopping cart so you gotta return it to get your money back.

Decree into existence an Online Bill of Rights. Includes things such as:

• The right to appear offline: this feature is mandatory in every social app, network or game.
• Read receipts are illegal. Let's go back to a time people didn't worry about "leaving them on read/seen"

I would also make society work on a two tier citizenship system.

• Statist tier: you pay your 40-50% in taxes and get your "free" healthcare, social security, "free tuition", etc.
• Sovereign opt-out tier: you pay no tax and relinquish right to any public social programs.

Let people sort themselves and leave each other alone.
