There was once a blacksmith in most villages. Now there are very very few. Blacksmiths do not shoe horses, that is the job of a farrier.
Anyone in the UK can set up as a blacksmith, to be a farrier you must be both qualified and registered. I would certainly have not allowed any of my horses near a blacksmith. In fact farriers have increased in numbers in recent years.There are around nine recognised schools and about 25000 registered farriers in the UK.

It is much more in the public interest to house desperate refugees than it is to build a railway track, in my view.

I would find it hard to fault your point of view.

There is no reason they cannot continue to do:
Well let us analyse that assertion:
1)criminality. A 2014 Irish Penal Reform Trust study produced in relation to Travellers in prison found a disproportionate number of Travellers are incarcerated. Men are between five and 11 times more likely to be jailed while, for women, it's 18 to 22 times more likely.
2)The one sure connection to crime is poverty.The Traveller association with criminality is relatively recent. The decline in the demand for tinsmiths, carpets and second-hand furniture has hit them hard financially.(Ireland)
3) lack of access to health and education.
4)The suicide rate for Traveller women is six times higher than the general populace. For men, it is seven times higher. Infant mortality is 3.5 times higher, life expectancy is more than 15 years less than average. As for education, two-thirds of Travellers have left school by the age of 15.
5)In theory, there is nothing stopping Travellers from staying in school. But the biggest obstacle of all is societal expectation. If your siblings didn't finish primary school, would you? Not to mention the practical difficulties of doing so if your family is moving around.

So by allowing their way of life to continue you subject the children to poor health, grinding poverty, high rates of depression, higher suicide rates, poor to non existant education, very restricted job opportunitie sand a severely reduced life expectancy.
Treat children in normal communities in the same way and they would be taken into care for abuse of their human rights.
The solution is to integrate them into the community so they have the same expectations and opportunities as the rest of the community.
You by glorifying the traveller lifestyle condemn their children to a life of misery.
