A landlord cannot just come on top the lawn and start ripping it up without the tenant's permission.
On one hand, yes. On the other hand that's only as enforceable as a tenant can fight it.
In practice it happens. Unless the tenant has the resources or there's a legal advocacy group dedicated to that specific issue, owners tend to be able to do whatever they want so long as they use the argument of 'protecting my property'.
The settlement and restitution just ends up something like the owner keeps their stuff there and maybe you get to terminate your lease tomorrow without being forced to pay out the whole eight remaining months of the lease. But that's anecdotal.
Clearly Obi-Wan is the master of the High Ground. He knows its strengths and weaknesses as second nature enough to exploit as he needed.
Anakin and Maul had no chance.
*edit To add: Obi-Wan gets caught in a fight on flat ground in front of Luke? Just gives up.
