There is no such thing as 'far' when the need for housing keeps growing.
The highlands of Scotland are a long way down the list for newbuilds I'd wager... Besides that's another problem entirely, reducing our population increase.
Any problems with farmed animals could be mitigated with a compensation system. It's not like this kind of thing is new and experimental, worldwide rewildening is increasing at quite a pace, including Lynx, bears and yes, wolves* in Central/western Europe along with Wolves in various states in the US, amongst others.
A healthy large carnivore population equalise the system and benefits almost everything.
They may also help deal with the masses of sheep on our uplands and in doing so reduce flood risk and insurance claims in the UK too. Alternatively we could just pay farmers not to farm sheep and allow woodland to be re-established on Britains uplands, using the money saved from not needing to build flood defences... Unfortunately there is little science in government policy.
*Wolves are re-establishing themselves well in Italy, France, Austria and Germany, and have even been tracked into The Netherlands (using radio collars) so suggesting they cannot exist in Western European nations is being proven to be untrue. The biggest treat is us to them, rather than them to us, as anyone that has ever tried to see wildlife will attest - it always runs.
why not re-introduce bears and wolves too while we're at it
but seriously, it might help cull the chav population![]()
That is the eventual aim, it would do wonders to the health of the countryside, especially the upland areas they would inhabit.
