That you are exposed while there is no known working treatment yet. Many attempts are in the works out even trials, but nothing proven. In the near foreseeable future, there might be one.

One reason to have the lockdowns.

No, the reason for the lockdowns was to increase the chance that people will find care in the hospitals.

I shudder at the thought of a government locking people up because a treatment might, at some point in the future, be found.

It is of course besides the point but I find it extremely optimistic to expect that a treatment can be found that will significantly reduce deaths when deaths mostly occur in patients of very advanced age or with significant underlying conditions.

Is there anything promising at the treatment front right now? My impression is that there was an initial group of candidates for repurposing that have on closer investigation all turned out to be not quite as helpful as hoped.
