That situation can be easily defended against by having mines/sats/fighters which can't be captured.

Your ships would already be heavily shielded, and you would likely add self destruct if you knew pirates were in the area.

You could always ram if your shields are about to fail, and security stations work well too.

Besides, If ship capture tech was so dangerous, why do you run around with phased polaron beams and WMGs, when you could just have a fleet o ship capture tech & a space yard to scrap what you can't support?

The pirates will have to do hit-and-run tactics on your lightly defended colonies and solo ships.

Anything you lose, you can replace.
Anything Pirates lose, they've lost for good.

So, in a straight out fight, the pirates will be crushed. The pirates have to completely win blowout battles, if they hope to capture more than they lose. You, on the other hand, can build more ships and fight back after losses.
