Just to clarify for some people, in polite company, a turkish house-tent is what we call a yurt, whereas a house-tent in mongolia is not a yurt but a ger. In France these are called shabadoos, in canada we call house-tents plumbuses, and in the US these are called fleebs. I personally get offended when locals see my shabadoo and refer to it as a ger.
For that money, you get a well-isolated easily movable tiny house in a country where you are allowed to settle everywhere (but if you have 2000 sheep with you, you should better discuss the usage of the pastureland with the locals) without paying rent (outside the city).
Choosing a ger for housing is not only about tradition and culture. It is quite rational in that situation.
