Because if worn correctly and changed regularly, masks catch the traces of the virus that you are breathing out and help prevent someone who already has the virus from passing it on to other people they are in close contact with.
The term 'close contact' is important. Walking past a COVID-19 carrier in the street isn't going to transmit it to you. Neither is meeting a delivery driver outside your house. Sitting next to a carrier for 15 minutes while they breath all over you and your possessions, food etc is. That's why even when governments are shutting schools, banning gatherings of groups of people etc. they're still saying it's fine to go for a run round the park or go out to the shops.
Wearing a mask on your trip to the shops to try and prevent yourself catching COVID-19 is completely pointless.
I don't worry for my own sake, because my immune system is top-notch, but my wife with many health conditions is immune-compromised and I've been trying to get her some masks for days now.
As above, her wearing a mask will do very little to protect her from COVID-19. The best thing she can do is wash her hands regularly (so that there is no virus on her hands), stop touching her face (as that will bring any virus on her hands into close proximity of her eyes, mouth, nose, ears etc.), keep the house clean (so that there is no virus lingering on the surfaces she and you are touching), and avoid being within close contact (2 meters) of other people for any sustained period of time (who might transmit it to her). If you bring objects into the house, particularly those that other people have been handling (e.g. food deliveries), you want to consider washing your hands after handling them yourself. Those are the measures that will help her avoid catching COVID-19.
The amount of use a mask is in helping you avoid catching COVID is absolutely minimal, and if you're not taking the above precautions then the mask will be 0 use. An ordinary citizen (i.e. not a health worker) wearing a mask to avoid catching COVID is like drinking more milk to avoid breaking a bone while playing football.
Instead, they are hoarded for health care workers
i.e. the people who are most likely to catch it and who are in regular close contact with people whose health is poor and who might die if their nurse accidentally transmits COVID-19 to them. And the reason they are being 'hoarded' for health care workers is because, as you say:
Around here, they're not available at any store, at any price.
If supplies weren't set aside for healthcare workers then the panic buyers will be sat at home on the toilet paper thrones wearing 5 masks on at once while health care workers have nothing.
