>If they can't be raised, and the costs end up being ruinous to the landlords, they will find other solutions like mass arson

Landlords who have their entitlements to land rents or other natural resource rents they've captured ripped away from them would almost assuredly endorse the use of violence.

Land redistribution (of which this is a form) from the landed rentiers to the landless has historically resulted in brutal violence in order to protect their privileged claim on non-human created wealth.

Why shouldn't people's property be protected?
