That just makes the state the owner of most of the society's wealth--which in practice means the small group of people who control the state own it. How is this better?
I base this on the number of new billionaires vs the number of major new political initiatives.
I think it’s quite easy to have a vision, but very difficult to filter those through the will of the people. In the sense that a great vision is very subjective and may not be believed by the large number of people necessary to change things in a constitutional republic.
History shows that such people are much, much rarer than people who have a great vision about how to use wealth they have either inherited or built up themselves for everybody's benefit. Or, to put it another way, people with a great vision that will actually work are far more likely to become entrepreneurs than politicians. Bill Gates is eradicating malaria using his own wealth while governments have failed to do so for centuries.
What they find disturbing though is that they as a society have to pay for all these property related services like internal protection (police, courts, law system) like external protection (army) and give these to the sitting and do-nothing landlords for free. While paying for them from their pocket through income taxes and receiving nothing back.. Actually the landlords are then so kind as to increase their home rents as a Thank you.
And it isn't random. You can acquire this property if you want. But be aware, you seem to be expecting to acquire the "entire society's wealth"...most of this land isn't that valuable and that land that is requires work (which is why it is valuable).
Again, I don't understand what your point is here beyond anger that someone else has something you want?
EDIT: Are you actually familiar with the population distribution and density in Scotland? A good chunk of this land is just agriculture and rough grass that has few economic uses. This isn't land that anyone wants to live on. The main concern of the govt, as I understand it, is to encourage forestry (which will mean more large owners, not less).
Why should large landholdings beyond individuals’ management abilities be left to particular families?

That’s not the point. The point is that a small group today shouldn’t be the inheritors of the entire society’s wealth. We shouldn’t be judging people today based on the actions of distant ancestors. And the way to avoid that judgement is for the majority of absurdly wealthy people’s property to devolve to the state when they die.
