The thought that someone could enter the place that holds everything I own is more shocking to me. If my landlord wants to enter my flat, he can ask me and I'll let them in - I can't make sure that my landlord doesn't enter my flat.

No but tbf you can point a camera at your door and Sue his ass off if he comes in without justification or permission.

Also an extremely American concept

I disagree with you. It is absolutely authoritarianism at the root of these issues. (As an American who has been observing this for some time.)

A few hours ago I was summarizing this article to someone in person and concluded with "but this country is very authoritarian", the implication being that the letter and spirit of tennant laws are not widely known, and the more authoritarian cultural norms, biased towards landlords, end up as the de facto rules.

"Pro-landlord" is not "pro-ownership", it's the opposite.

Oh sweetie, oh no...

The landlord IS the owner.

They are inseparable. You cannot be pro-landlord and anti-owner, or pro-owner and anti-landlord.

"I'm pro-developers but against programmers!"

"I'm anti-programming, but pro-coding!"

Come on now.

Oh, come on. Most houseowners aren't landlords (people who own multiple properties and make money by renting it to others).

It is in the interests of landlords that as few people owned property as possible. This being pro-landlord is being anti-ownership, numbers-wise.

I'm pro-owernship of property, I'm anti-getting-rich-off-mere-ownership (that is, quite literally, rent seeking).

Someone who only wants the police to have easy access to guns is anti-gun ownership.

Someone who only wants landlords to own property is anti-property-ownership.

And being pro-landlord is exactly that.

TL;DR: all landlords are owners, most owners aren't landlords. And the rent is too damn high.
