The virus is in animal hosts already, so it probably won't be eradicated. Even if it wasn't in animals, there are countries with principles of freedom where some 10-30% won't listen to a lockdown. It's unlikely those countries will all change their foundational cultural principles. I don't think technology is the only factor, think of looseness and tightness of cultural behavior, think of self-regard vs regard for others. These things matter, it's not all about grocery delivery and Zoom meetings. Especially for the meat-packers who make the groceries in factories, and the healthcare workers who need to go in to the physical clinic, etc.
Somehow New Zealand is a special country with principles of freedom. I failed see that how it is culturally fundamentally different from other western nations.
IMO, the acceptance is mostly linked to the effectiveness of the initial implementations of the lockdowns. And the effectiveness is seemingly only determined by the initial strategies. Countries which went for elimination/eradication had better outcome, and thus higher lockdown acceptance. In countries which went on flattening the curve, people had the same (if not more/longer) disturbance, but less success (more deaths).
