I knew you were gonna point that law (that no one but TBH enforces, so much not even devs considered them before implementing Kidnapped VIPs) and it doesn't hold much, Kidnapped VIPs already take 5 cargo space per unit, you cannot carry, say, 5,000 of them in a 5Ker, only a fifth of the total cargo hold of transports there's no excess of them, even though it's also not defined exactly to what extent it is considered "excessive" or not.
TBH laws also do not mention ransom/Kidnapped people that INRP the Corsairs THEMSELVES pay for to get to ask for money, the "no mouths to feed" doesn't hold on this case, ransom victims are not immigrants, and you can say whatever you like, everyone knows exactly why you're doing this.
