Fair point about the price bump, but I'd be very surprised if 9/10 of these "kill me" traders really care about a few mil here and there, they're probably swamped with obscene amounts of credits through relentless ooRP powertrading and would as I sort of implied before probably rather lose 20mil worth of cargo than hand over a single credit to a pirate.
I personally think some sort of regulation of piracy demands is a better way to deal with this, then it is all on the traders to act inRP, or get sanctioned. (Don't ask me what sort of regulations though, I realise some people do piracy to make money, that's fair play and shouldn't be nerfed to the point it can't be done)
