Regarding driving down future demand: not likely more than in the very short term... flour has a fairly short shelf life. Have you ever used/tasted rancid flour? While it's not the end of the world, it's not something most people are likely to want use in a recipe more than once given a choice.
Based on?
> not likely
Again, based on what? Your intuition? You have some data correlating flour purchases with people unable to bake (and apparently unmotivated to use a search engine or read expiration dates)?
Storing flour in a sealed container extends its lifespan. Freezing it even more so. Anyone can easily learn these facts if so motivated.
Listen, I don't want to over-generalize but I've seen this on the Internet about the most mundane of skills: cooking, baking, doing your taxes. They're all just instruction-following. Sure the upper limit on the skill level is high but basic competence to get a usable product on all of them is like at the level a twelve-year-old could do it if they had the motor skills.
There are lots of people using flour who didn't before, but lots of it is going to go to waste.
