Here's some good news on treatments: Inhaled steroid Budesonide reduced risk of patients needing hospital care by 90% when given in the first 7 days of symptoms.

Based on the number need to treat and the cost of the drug, giving Budesonide to everyone who has a positive test would save 1 hospital admission for every £120 spent. A hospital admission costs a lot more than £120
I was part of a larger trial for the same thing, conscentrating on older adults and those with comorbidities. It is still running, if anyone is eligible and wants to volunteer. You have to be either over 65, or over 50 with a relevant health condition. See here
The sooner the trial completes, the sooner treatment policy will change. Along with vaccines, this could all but eliminate sever Covid needing hospital care.
