Its all about added risk.
Don't want to lose your claim, then manage it properly. Keep it safe and don't expand it needlessly. The new system also allows people to transfer claims, which is a good thing.
Don't want to lose the 10 million LP you have in your main. Maybe its a bad idea to raid/grief some lonely hermit just because you stumble across their hideout when you're low on HHP. Risk vs reward - not a bad thing
BTW, it might be overlooked, but you also inherit Yeomanry which means everyone essentially keeps a base 4000 LP. For top-end players that's nothing, but for the new/casual its a decent keep.
