This is a great reminder of how important it is to support local farmers and small operations, which increase the resilience of the system as a whole.
We have not experienced the massive increases in pricing on eggs. The supply management system effectively works to keep farms roughly below a certain size, and seems to have helped avoid large impacts on certain staple foods.
The usual rhetoric against this is that we should be getting cheaper prices by letting in foreign competition. This ignores that doing so would allow foreign subsidies to wipe out our local supply of critical foodstuffs, then making us dependent.
It's not an ideal system but it seems to have yielded some tangible results when things like bird flu are making their rounds.
