Also, in Iceland, where they have tested widely (and without regard to symptoms), about half the patients who tested positive have been asymptomatic.

Not quite right. The tests run by the government use somewhat similar criteria to the criteria used here. You get tested if you are symptomatic or if you have been in close contact with someone who has COVID-19. Such persons are more likely to test positive than a "random" individual. The tests run by deCODE Genetics (Amgen) are open to all. About half the tests run in Iceland have been run by deCODE. I do not know what test is being used by deCODE, or what controls they use. deCODE says they plan to test at least 50,000 individuals (13.7% of the population) before they stop.
