Is There A Word "Depropertization"?

I spotted this in the Museum of the Underground Prisoners in the former Central Jerusalem Prison in the Russian Compound.



Is there really a word like that, "depropertization"?

Well, I found this academic article:

The generally disappointing outcomes of privatization can always be explained away in terms of ‘institutional’ shortcomings, but the real challenge is to devise more flexible property rules to deal with diverse goods and local environments. The rest of the paper notes some of the most salient anthropological contributions in a range of other fields, including intellectual property and ‘culture’. While some scholars reject the concept of property in non-Western contexts, recent work in legal anthropology has laid out a rigorous definition that facilitates comparative analysis and exposes the limitations of the currently dominant economistic approaches. ‘Propertization’ is continuously establishing new ‘fictitious commodities’, but it is argued here that some critics of neoliberalism exaggerate the nightmare of its property logic and overlook the countertendencies.

and then this:

P. 10 -

Functionarization and to a large extent depropertization of dominant groups in the XIX century as major tendency, much more important for Russia than awkward development of capitalism during that period

and also this:

Obama's job is to take you away from anarchism, not towards it. And he's is for more dangerous because he uses far more deceptive means ("localization," "hope"). Let's remember the history - the welfare statists were created by the elite to keep revolution (depropertization) at bay.

Hmmm.

I would have used simply "arms expropriation".

I think the translator was being too literal and was a Hebrew speaker using a good dictionary but the word is too 'superior' and doesn't fit.
