It isn't an option at all because the situation will continue to worsen for at least 18 months.
This is a pandemic of a new strain of virus and it kills anywhere between 1 and 8% of those affected. It will become endemic in due course and be managed via vaccinations in the same manner that winter flu is now, with annually updated versions of the vaccinations to meet the changing nature of the virus as it mutates.
The initial vaccinations will take more than a year to develop because, as with all such medications, extensive trials need to be conducted before they can be released for public use.
In the interim, if countries don't take extreme measures to curb the acceleration of cases then the ability of medical services to deal with it will become overwhelmed and we'll have so many deaths that mass graves will be in use.
If it kills 1% of the UK population, which isn't beyond reasonable expectation, then that's 660,000 people dead. A disaster scenario (say 80% of our population affected and a 5% death rate due to no medical capacity to treat) would be circa 2.6 million dead.
This is a bad situation that will get worse before we get to a point where it's manageable. It'll change the way we interact and travel, not just for decades but forever.
