I've been baking bread under quarantine when I haven't in the past been a baker on a regular basis. What it does is allow me to extend the time between grocery store visits; the usual choice is to buy less frozen food so I can store a loaf or two of bread in the freezer, instead I can fill my freezer and bake when my bread runs out.
I'm doing this quite explicitly - on my last shopping trip I bought one loaf that went straight into the breadbox. When it is gone it will be replaced by a baked loaf.
I don't know if this thinking is common, but obviously extending the time between grocery store visits is a good thing.
tangentially related: I think there's been a lot of unwarranted gleeful bashing of people as universal stockpilers when I suspect that most of this is a tempo/timing thing (which easily destroys a JIT supply chain.) It's not that most people were stockpiling unnecessarily, it's that everybody was shopping at the same time, and fully stocking their larder rather than doing it as casually as they usually would. The special cases of particular staples like toilet paper were intensely covered by the media, IMO creating the hoarding of those staples. In normal times, if I have three rolls of toilet paper at home and I'm at the grocery store, unless a sale jumps out at me I'm probably not going to buy - I only buy when I'm critically low. In current times, that would be a bad move that would result in a special trip just for TP (which would be trivial in normal times.) Not buying the largest size of TP available (which is only around $20) seems reckless under the circumstances. If I hear that people are stockpiling, I might want to buy more than one for fear that when I need TP, I might have to travel from store to store to find it, exposing myself even more.
I'm saying this as somebody who always buys the largest size unless there's a sale that makes a smaller size cheaper by sheet, went shopping a couple of weeks before any quarantines were announced, and therefore hasn't had to buy any during the pandemic. The fact that I was able to make it 5 weeks on what I had at home before going out again was a comfort.
