I don't deny that coercive relationships exist... but I'm talking about "roots" like tool usage and cooperation in communal animals such as primates. It relates to the context of property ownership because animals mark their territory and use violence to enforce it. Hence why property as a concept is fundamentally violent.

Object ownership isn't as fundamentally violent the way I see it.

I'm not exactly sure what you're saying other than land ownership started as violent and tools were shared in small tribal collectives. This seems muddied to me. I don't think small tribal bands protecting territory or sharing tools with their own tribe translates to a modern rental contract. There is no reason to believe that the origins of those behaviors should trump the reality of how these systems function today.

Today, object ownership allows a person to claim authority over an object that is in someone else’s hands. An ISP can remotely disable a modem. Or a manufacturer software-locks a tractor. This is territorial dominance.

In primitive societies, everyone had access to the tools that allowed them to function and survive. Today, you can be excluded from those tools. The exclusion is the violence.

Renting an object grants someone else the legal right to "mark territory". This is not like a person letting another tribe member use the communal tool they just finished with. Those tools were communal and not private property. Renting an object is part of a fleet of tools you don't use or plan to use. They protect that profit stream like a pack of chimpanzees patrolling their territory and evicting intruders with violence. modern owners can rip a tool from your hands by locking you out remotely by executing a script.

TBF One could also argue that ...

Are you making this argument? Should I spend time addressing it?

Landlords as the people who rent out places to live to other people are responsible for the house. It's not raw unimproved land. Houses need to be built. They're objects with many moving parts, subject to a lot of technical challenges, and code enforcement.

If you allow that object rental has a place in society, I struggle to understand how houses are not ethically the same as renting lawnmowers. You can be a predatory arse or a fair dealer about any rental situation.
