The old man who finally introduced himself as Gregor was kind enough to give Gio three days of freedom to decide what he wanted to do.
He also made sure to make their stance clear.
"You are not obligated to return. If you wish to stay here, you can. However, your recent actions have become concerning. If you wish to keep exploring the Wildlands, we will not be allowed to leave you here without protection."
In other words, Gio could stay in the Wasteland as he wanted, but he couldn't keep living so freely. He'd have to be followed by a protection detail that assured his safety.
Naturally, that wasn't his way. He knew that if he went to Arcadia, he would have a lot more freedom than that. More importantly, Arcadia was a hub for talent. Elysium was too unreachable, so the 2nd Stratum was where the majority of humanity's talents gathered.
He would be able to establish roots in many places when he was in Arcadia. The plan to save humanity would finally start progressing there.
