I agreed with you at first but reading through Urbit's docs and the vox article linked in thread clarified the relationship between the system design and the author's political ideology. Many of the design choices did not make sense to me until I understood that the author basically leads a thought current around a return to aristocracy.

With that, there does seem to be some reason to avoid the software simply because it may be designed to produce a particular political outcome.
