I think you're slightly off track as to the frustration with lack of testing:
Let's start with widespread complacency opposed to requests to take distancing measures: people (not me, but .. read FB comments from regular people on news stories) are mad at sports events being canceled because "nobody has the virus". So we don't get the social distancing response needed.
If on the other hand we had some testing data from the general population, or even from just mildly sick people, then the requests for social distancing could be presented with "and we know this thing is here now, so these measures are going to have a significant effect".
