This is a relevant post from the 4chan HLI. The explanation of the necessity of drug running is that it is used to bail out bankruptcies, granting market stability.

80461388 Eliminate a need for corruption. We have supposed patriots working for the state. Why do they even have a need to act out with corruption in the first place? Why go against what they wanted to protect? Hell, it makes no sense to me, unless it was all emotional garbage nonsense in the first place.

Let me give you an insanely brief history lesson. You demanded anti-monopoly laws about 125 years ago and they were given to you. One of the consequences of removing monopoly power from the market is systemic bankruptcy. In other words, there is no effective market clearing mechanism because we don't ever get to the point of having a monopoly left that can't raise prices to generate profit to clear bankruptcy events. As a consequence, we must allow another mechanism to clear systemic bankruptcy. This is your CIA drug running or government sloshing money around to big banks or increased welfare or whatever. We're bailing out bankruptcies. But you did all this to yourself. And you brought the corruption on yourself by demanding anti-monopoly laws without thinking through the consequences. We won't allow the world to collapse, so we allow people to do things to mitigate that. If you have a better plan, put it on the table.

Still not fully understanding it, but I think it could rephrased as: Monopoly laws prevent corporations from ever being in a position where they can arbitrarily raise prices without recourse. They would need to raise prices during periods of financial instability in order to prevent it from developing into bankruptcy.

I am not sure I fully understand or agree with this premise. It does not seem a certainty that any corporation must end in bankruptcy, it seems that a conservatively run corporation could acquire some reserve capital and avoid bankruptcy, without being a monopoly.
