That is not the case for poor countries.
Due to corruption, inept leadership, misapplication of funds etc etc etc (lack of resources in poor countries ranks well below things like corruption and bad leadership), poor countries simply cannot experiment.
A good example of what happens when things go wrong in a poor country is Ecuador, where they are leaving dead bodies in the streets. The link below shows how things have shat themselves in Ecuador:

Bottomline - wealthy nations like the US, Italy, UK etc can see if there are more efficient ways to solve the COVID19 situation without locking themselves up in fear. But countries like Malawi and other poor countries in Africa, Latin America and Southern Asia would probably find it prudent to lock up, feed the poor and see how the wealthier nations of the world resolve COVID19 first.
Rich countries have bad demographics for this virus warehouse their elderly, and coddle immune systems. They also are able to print money and give a few months wages to many people quickly and without immediately causing hyper inflation.
Ecuador used to be a more prosperous country.
It also wouldn’t surprise me if Ecuador was already leaving a few bodies on the street.
On a thread about the four inner-city Atlanta hospitals being over capacity with people on beds in the hall, someone pointed out that this was not an infrequent occurrence before anyone had heard of COVID 9.
FAR more people have died from the flu this year, so why the paranoid concern over this virus??
