> Russia can sustain itself if it wants because it is so large, so it appears they are attempting to build some sort of enclave at any cost.

Likely, though not like they are not dependant from outside world, i.e. they can become soviet union 2.0 with iron curtain 2.0.

Their commercial aviation is dependant on boeing and airbus - no parts for foreseeable future. Big portion of shipping containers will stop coming, banks are restricted and foreign money is pulling out (moscow exchange is closed for the 4th day), etc.
