Some of this is direct from land use regulations. Some of this is from political influence of Fire depts.
It's only recently that people are waking up to how the regulatory requirements of staircase design in multi-family buildings for the ostensible purpose of evacuation impact the look and feel of US cities.

Also, what is the long term fate of such tribes? Without genes flowing in, it's probably not good.
I wonder about a protocol that a high technology civilization could use to contact them. Priorities would be to avoid violence, disease, misunderstandings and so on but at the same time, to allow them enter into the modern world over some generations.

In no sane world should this not be punished severely.
