And of course, it's a political stunt to please Edrogan:

The Kurdish refugee journalist Vedat Yeler has called the eviction and destruction of the Lavrio camp a “NATO gift to [Turkish autocrat Recep Tayyip] Erdoğan.” The eviction took place only a few days before the summit of the North Atlantic Treaty Organization on July 11 in Vilnius, Lithuania, where both Greece and Turkey were to be present. The two NATO members have wrangled over the Cyprus conflict and territorial disputes in the Aegean Sea for many decades. In mutual populist slander, Turkish politicians have been accusing Greece of harboring “terrorists” in the Lavrio camp and pressuring the Greek state to close it down for years. However, since the re-election of both Erdoğan’s Sunni-nationalist regime in Turkey and Mitsotakis’ New Democracy government in Greece in May and June, 2023, respectively, there has been a shift in bilateral relations between the two countries. During a visit in Cyprus a few days before the eviction, the Greek Foreign Minister expressed a commitment to improve relations with Turkey. The attack on Kurdish political refugees in Greece can be understood as an attempt to showcase these efforts before the NATO summit.

Greece should be ashamed of itself - evicting innocent families at gunpoint to appease a foreign autocrat. I'm not familiar with EU law, but I'm hoping someone in the comments has an analysis and legal case for the Lavrio residents - given that the camp was established community for over 50 years, there has to be some legal recourse they can use to push back.
