You first implied that there are plenty of rules that are completely pointless - mitigating no negative externalities. I challenged you to provide an example of a start-up whose business was based on breaking those kinds of rules - since usually the reason you can make money off rule-breaking in the first place is because you're externalizing the costs onto the rest of society.
I then said that rule-making is a trade-off, and that you don't get to unilaterally decide those trade-offs are illegitimate because you want to make money. In the case of medical marijuana, yes, obviously, there are negative social consequences to selling marijuana and there are people who would vigorously argue in favor of federal drug laws. But these clinics are not unilaterally operating in defiance of federal drug laws; they have the backing of the government of their states.
Of course, there are also plenty of profiteers who just break the law and then reinvest the profits in the task of forcing communities to accept their social irresponsibility and lawlessness as a fait accompli (AirBNB, Uber).
If you really want to think seriously about these issues, you need to move beyond just name-dropping 'logical fallacies' to try and win arguments.
