I think it's more complicated than that and the people decrying "wasted" negative tests are [redacted] idiots.

If you're at home with what appears to be a relatively mild case of COVID, testing you doesn't tell us much right now[0]. Isolate yourself, even from your cohabitants, and scrub everything like the dickens when you feel better. You should be doing this anyway, even if it's "just" the flu.

Testing people that were around you, however, is critical for preventing the virus from spreading. This is especially true for people are asymptomatic or presymptomatic but nevertheless shed the virus.

[0] This might change in the future as we learn more about if and how long the immunity lasts; perhaps you could go back to work. Hopefully sereological testing will fill that gap soon.
