I don't disagree, though it does come down to cost-benefit. Masks are a no-brainer IMO; they're cheap & data generally leans towards them having some level of efficacy even at the lowest ends of the cost-spectrum (ie cloth coverings), and they appear to have rapidly-increasing efficacy as the cost-spectrum value rises (ie N95+, respirators, etc). I should have included the last sentence from that paragraph in the study, because it's pretty concise: "Therefore, careful consideration should be given to the cost‐benefit of implementing such measures." IMO it'd be impossible & fruitless to attempt to get even moderate numbers of businesses to do health & temperature screening, much less small businesses; it's just cost-prohibitive, and with the benefit being mediocre at best, there are likely better places to allocate resources.
