Several of my friends and colleagues have made comments such as, "we need a long lockdown for coronavirus to disappear!" and "why do people keep going outside, we will never stamp it out to zero cases." Or "people breaking lockdown will mean that coronavirus is never stopped!"
Whilst I understand the lockdown is important for managing the number of cases, it is my understanding that the lockdown was never to completely rid us of the virus. It will still be there after lockdown- We will have to learn to live with it. It'll be a significant part of our lives until there's a vaccine, or effective treatment. Lockdown was just a temporary measure to curb the initial outbreak ripping through society and give us time to prepare.
One of my friends genuinely believes that if lockdown gets the cases down to zero, we can immediately come out of lockdown and carry on as before. 
I tried to explain that it wouldn't work, even if we miraculously got zero cases- ie, when flights start up again, it'll come back from somewhere! And how can you possibly ensure no one in the country has a virus? You But no. Same friend even suggested a "worldwide coordinated lockdown."
Am I BU to not understand how people can still think this? They watch the news everyday, it's not like they're keeping themselves in some quarantine bubble. I understand we are trying to slow the virus and stop the curve but this does not equal one singular lockdown to eradicate it.
