That's because there is no organization or infrastructure to crush. These are guys in fishing boats. You can dispute the effectiveness and the energy of the response if you want, but large numbers of pirates killed and captured, and a 90%+ reduction in attacks on commercial shipping and a 100% reduction in successful attacks sounds pretty effective to me.
There is always organisation, there are the financiers, the organisers, and the gun-men. Take the criminal network away and it takes much longer for the activity to resume.
There is always infrastructure, however primitive it may seem to us.

Yes, and every one of these pirate attacks have a summary report that is available. Here are a couple of samples:
Yes, most "attacks" are petty theft, by the Times article something like 80%, but there are also real piracy e.g.:
23.06.2017: 1300 UTC: Posn: 03:55.2N – 103:52.8E, Around 33nm ENE of Kuantan, Malaysia.
A tanker enroute from Singapore to Songkhla, Thailand was boarded by six pirates armed with guns in a speed boat. They took all the crew hostage, hit a few crew with their guns and damaged the navigation and communication equipment. They then sailed the tanker to an unknown location where part of the gas oil cargo was stolen and transferred into another vessel. Before escaping the pirates stole crew personal belongings and ship’s properties. After the pirates departure, the crew sailed to a safe port.
But if one or two out of over 100000 ships passing the area every year is hijacked it is not noticeable.
Most attack fail, and no real attempt to find the assailants is undertaken.
In Somalia it took almost ten years of attacks, including about five years of noticeable attacks, before basic patrols to suppress the pirates. Some attacks have been prevented, including killing a few low-level gun-men, but no successful pirates have been tracked down. The swift and energetic response is obvious by its absence.
If the same swift and energetic response happened in Traveller, warships would start patrolling the area infested by pirates a few years later, making no attempt to find the perpetrators of earlier attacks. Any pirate attacking a few tiny ships in backwater systems, and then moving on should be rather safe.
