>It might even be logical with the above 3 steps in place for zero/low risk group to deliberately seek out the virus. This grants immunity quicker, and if they become sick, they can receive treatment whilst hospitals are still underwhelmed.

This is extremely irresponsible. The long-term effects of the virus are currently unknown but there are some worrying signs of possible long-term lung and other-organ damage that have been reported (anecdotally) from China and Italy. It's going to take time for these studies to be done.

Not to mention the immunity period length is unknown at this time. If this coronavirus follows the pattern of other coronaviruses, immunity could last 6 months to a year tops. That is ... not good. And a secondary infection could be worse than the first due to immune system overresponse/cytokine storm.

It's important we take the time to study these secondary effects and allow time for treatments and/or a vaccine to be developed and studied before we come up with any long-term plan.
