My P-Claims (2) are small and not strategic. They purposely do not cover any useful resource (other than what I can create). I kept them active to do exactly what I have done, log back on for a few weeks and mess around, have some fun.
But that time will soon come to a close, and when it does, If this world is still around, I plan on posting the claims in Dwarves and Thieves, making them available to another new (or renewed) player as a starter base.
I am just mentioning this here as an alternative option.
And yes, if I get no takers, or (gasp) only trolls, I will simply unload into storage all my alt-vault goodies, de-claim and exit.
