"Ergo, they are no longer travellers"
Yes they are - the permanent sites set up in Britain fully recognized the Travellers need to travel and made full allowance for the residents to continue the lifestyle they were born into and allow them to leave and return to their allocated sites at will.
Moving Travellers into houses is extremely expensive and satisfies neither the Travellers nor the settled community who do not wish Travellers to be settled in their area.
Most Travellers to not adapt well to living in houses and the mental and physical health issues arising from forcing them to do so are well established; the Leicester University survey above touches on them.
The 'solution' here in Ireland has been to build €multi-million walled ghettoes - hasn't worked for anybody.
The simple and by far most economical policy is to supply halting sites with hard standing and basic access to facilities; running water, sanitation and electricity - go and look at the ones outside Swindon or Bristol (Winterbourne), or any other properly established permanent site.
Most of these have been set up with full consultation of Travellers themselves, a practice that was implemented in the late sixties with the introduction of the 1968 Caravan and Camping Act.
Your Cairo shantytowns are the result of having no planning policy.

You going soft Richard - only the 20th century? She remains the Rosa Klebb of British politics, lacking only the poisoned boot.
