You could tie essentially any two crimes by assigning more broad descriptors to them that'd boil down to "this is what countries want to discourage". Not to mention, half of this is just wrong - digital piracy most often isn't extraterritorial (it very much falls under the jurisdiction of where the piracy took place), and most individuals pirate for personal needs, not profit.
The point stands - no jurisdiction that I know of treats digital piracy similarly to naval piracy, and there is no strong argument in favor of doing so.
Mostly committed by private citizens in pursuit of profit
That all nations of the world have an interest in suppressing to encourage free trade that economically benefits them
But which some countries at various times have a geopolitical interest in supporting
... you're right, they have no logical or legal connections at all.
