They are the only owner and can sell all of it

You can’t get a lordship just by owning land and you can’t sell a sq meter of land who cares what trust pilot says?

I can’t for practical purposes leave I’m poor and my wife is disabled

This is bullshit logic. We as adult humans already exist and have little choice about national housing policy. We can however choose not to contribute to suburban sprawl OR murder cats roaming the neighborhood whacking the wildlife. We can also choose not to have 12 children who will need space too. Not being able to do everything is a poor reason not to do anything.
