This is like suggesting the solution to plastic pollution is recycling and reduction by individuals. You can't regulate your way to changing people's behavior, but you can regulate away the source of the problem.

Individual action isn't the solution to a systemic problem, because there's more incentive to cause the problem than to fix it. Individual action requires time, money and effort on behalf of the individual, whereas the ones causing the problem have financial incentive to continue causing it, in greater amounts.
