As mentioned in stream - question about claim price is still opened.
We have an ability to rebuild claim totem and replace older one, so will be easy to rework it:
Make it so that there will be different type claim totems, each type will have maximum land size, soak value, and lp cost for it.
Let basic claim presented in game have 5 soak value and ~1000 hp.
So people will decide - if casual hermit need a small space for living he will not pay much for claim. But if big company of players will to claim clay/sand - they will need to pay for stronger claim pole.
