Second, there doesn’t seem like a clear “boundaries good” or “boundaries bad” story to me. Keeping a boundary secure tends to impose some serious costs on the bandwidth of what can be shared across it.
Hence “membranes”, a way to pass things through in a controlled way rather than either allowing or disallowing everything. In this sense absence of a membrane is a degenerate special case of a membrane, so there is no tradeoff between presence and absence of boundaries/membranes, only between different possible membranes. If the other side of a membrane is sufficiently cooperative, the membrane can be more permissive. If a strong/precise membrane is too costly to maintain, it should be weaker/sloppier.
