The curve may follow the same patern, but the countries that locked down hard and early, have certainly had a lot less cases and deaths than those that waited too long to shut up shop.

I agree that lockdowns slow things down. I also think the virus was circulating in places like New York long before they even thought about locking down.
Anyway, the similarity of curves in diverse places suggests something else is at work. The large numbers of asymptomatic cases estimated by various antibody studies seems to indicate the virus is more contagious and less deadly
and that a large percentage of people have some kind of preexisting immunity.
