I am all in for spreading the population sparsely under the sun for a month(I'll take the Greece beaches or the French Riviera). We can make the immunes ones prepare the food and bring the beer.

Well that's a large swing in the other direction, but I enjoy the hyperbole. You do realize lockdowns are the far other direction though? Do you see my point why lockdowns were bad?

Allowing and encouraging people to go outside is the happy medium.

The idea is to separate people from each other for long enough for the virus to die off. Could be done in many ways. Accommodating people in small separate groups for a month under the sun has it's practicality issues but if someone can pull it off the results would be exactly the same.

That idea is stupid when the high density areas live in multi-family housing.
