I think it's important to understand that while it's definitely not good that asymptomatic spread is a thing, it's worth considering what the real alternatives where.

For example in the USA, by only testing the highest risk categories, the positive rate is still only ~3%. Increases in the population screened will eventually lead to decreasing the positive rate. In that sense, broadening the criteria by which we do testing will lead to dilution of utility of resources. That's not to say that the choices we made were optimal, but rather to say that scaling our testing to the point where we are catching a significant portion of asymptomatic carriers may not have been the best choice.

Remember that both test consumables and testing capability are not unlimited.

You can model this out at home with different asymptomatic carrier rates and different transmission rates and find the optimal resource allocation for each case.
