[Star Wars] Why did the Seperatists bother blocking off Iego from the rest of the Galaxy?

In the Clone Wars episode "Mystery of a Thousand Moons" it is revealed that the CIS drove the angels from their moon put a complex death star like security system on it to keep the people of Iego from leaving. It doesnt seem like Iego was a very important planet, being described as a backwater and really only notable for spice smuggling. And when they left the CIS left hundreds of droids behind. The whole thing seems like a massive waste of time and resources so why bother keeping like 15 people trapped?

They probably had some idea where the blue shadow virus cure was, and in anticipation of restarting the project they took steps to lock down the planet so that they would be the only ones with access.
