As I don't daytrade, I wasn't aware of this rule. Is that 3 trades a day, a week, or what?
I guess the conventional wisdom would be that while you can make an "insane" amount of money this way, you can lose an insane amount too. That would be tougher for someone with a $25,000 brokeage account than someone with, say, a $500,000 brokerage account. But I can see that while the rule protects the little guy, it also makes it impossible for him to score a win. I'm not sure I would call it "warfare," though.
