It does seem plausible that requiring an in-person team to switch to IM and other electronic communication would be more difficult than starting out remote.

I work on accessibility for people with disabilities, and I'm blind myself (well, legally blind), so I think a lot about including people with disabilities. It seems to me that working with people with some kinds of disabilities, e.g. deafness or a severe speech impediment, would be akin to forcing an in-person team to switch to IM. (I have no direct experience working with people with those disabilities, so I'm happy to be educated.) So I speculate that starting out remote would also make the team more inclusive in this area.
