Profiteering is undercutting every possible thing. The profit motive over a democratically planned economy is horrible most of the time but really becomes a mess in a crisis.
Why not have bread lines only in a crisis, when you can have them all the time instead?
The OP was literally advocating for a centrally ("democratically") planned economy. Having production dictated by the political process as the default is the extreme position.
Developed countries all find some balance between central planning and laissez faire, but they do so by assuming the free market as the default. Intervention and central planning is only applied to specific cases where there is a concrete public interest in doing so.
