On the land value tax, you have to pay more tax specifically because its value increases. If you want to cash out, then sell the property for it's now much higher value. The value didn't increase because something you did personally, rather because the whole area became more popular due to you and your neighbours (or more usually, your tenants) moving in and being productive. It seems fair that this value that everybody added to your property would get distributed to everybody instead of just you, the owner.
