Are you sure about that? If that was the case, how is there so many large family owned estates around now?
Certainly after both wars, when many estates were crippled by death duties, the government BOUGHT, or took in payment for death duties, land and split it up into rented smallholdings for returning ex-servicemen. Sadly they didn't bother to offer much in the way of support and training and many gave up. Most are now just houses, with the land amalgamated into bigger holdings
All over Scotland there are these "holdings"; one at Tealing, near Dundee; one just outside Perth; Sauchieburn, just outside Stirling; Greenhill, at Kilmarnock.
