All civilised societies recognise and cater for differing cultures - it is the uncivilised one that enforce conformity.
Catering adequately for a substantial mobile population can be done at a fraction of the cost as that for a settled one. Go on to any well organised Travellers site and you will see that is obvious.
Using your logic, when the mining industry collapsed some years ago, the logical action would have been to demolish the former mining villages and move all the occupants into the cities and towns where they were likely to find work. I wonder what the reaction would have been to describing life in somewhere like Orgreave or Birtley as a 'pickled culture' and forcably moving out the residents!
Within living memory - certainly here in Ireland, Travellers were an essential part of rural life. When the trades they followed were made obsolete they adapted (far better than other social groups that have undergone similar changes). What they have not been able to cope with is the vicious prejudice that has sprung up towards them, both from officials and from the settled population in general.
When Ewan MacColl and Charles Parker were making the radio ballad 'The Travelling People' they recorded a Birmingham councillor and justice of the peace named Harry Watton. Regarding Travellers, who, he stressed, were nor 'real' gypsies, he said, "You can help the broad mass of these people, but those who will not be helped should be exterminated'.
Symbolically, his quote came almost at the end of the programme.
Here in Ireland Travellers are not provided with anywhere near enough sites, let alone running water and sanitation, so they are forced to camp illegally. If they do this their homes are impounded and in many cases they are imprisoned. If they move into houses they are driven out by the residents - so they end up in ghettos in the middle of nowhere. They haven't yet been made to wear yellow stars or carry passes but....
Many of them (asylum seekers?) move to the UK where conditions are marginally better. Those who stay live in Third World conditions.
Perhaps you might offer a (final!) solution.
