I was just reading about a violation of the Canadian fisheries act that has a maximum penalty of $200k, and realized the absurdity of there ever being a maximum fine.
There should be no maximum fine on any corporate penalty given that we do not cap the size of corporations or their bank accounts.
It would be like having maximum jail terms of 25 years for immortal beings that can live to 10,000.
The OP is proposing that there shouldn’t be a cap specifically because we don’t cap the size of corporations.
That doesn’t require that the size of the fine scales to the size of the corporation. The size of the fine could also scale to the size of the harm. A cap means that a company can inflict trillions of dollars of harm but only pay the fine up to the capped amount. That will usually lead to larger companies paying larger fines because they inflict larger harms, but not always.
But you just don’t want to engage with the topic of caps at all.
