Then WHY ARE SO MANY EXPERTS TELLING US WHAT I QUOTED?

What you say (and others too) makes sense to me and I could well believe it true, but I'm NOT claiming that masks are useless unless you are infected, I'M ASKING IF ANYBODY KNOWS WHY EXPERTS ARE SAYING OTHERWISE (or whether I just heard an unluckily skewed sample)

Plus, I also asked for a citation to back up the poster's position, not common-sense arguments (which are a good starting point but not evidence in themselves).

Which experts are saying masks are not effective? From what I read the experts (curiously from countries that did not prepare enough masks for their hospitals) say it is not recommended for the general public to wear a mask. They definitely still recommend nurses, doctors, and sick people to wear one. But they never explicitly say that masks do not reduce transmission. They may have said "there is little evidence to suggest..." which is not the same as masks do not reduce transmission.

The official position for many countries that are containing the virus suggests wearing a mask when out in public. One notable exception is Singapore.

Here is the Korean society of infection FAQ that says wearing a mask can reduce transmission:

Thanks, I've updated my original post.

Masks may be 100% irrelevant for healthy people, but we have asymptomatic people. There is no way to ascertain who is healthy, ergo "healthy people don't need masks" is practically redundant. What am I missing?

Oh, and you want citations, sorry, my bad:

See my reply https://news.ycombinator.com/item?id=22701821 Mind, I just don't know if what I'm saying there holds water.

Citations are good, following up!

I imagine to prevent mask shortages and to make law enforcement easier.
