You don’t need me to tell you that. You wouldn’t believe me anyway. There are plenty of professionals who have studied and acquired factual data of how other “perfect countries” do it and the differences. From the differences the solutions become very clear.
It’s about restricting access, not banning. There’s no one size fits all solution because nothing is perfect so you pick your poison. Find a country where this doesn’t happen every day (so any developed country), look a the way they do things and pick the one you prefer to support - they all have upsides and downsides. What you have isn’t working though.
