> What's the business value argument for not using Elm?

The time and energy investment into using any JS code in Elm for things not currently sorted out is severely disproportional to the value provided by Elm. The ROI is just not there. If you compare it to the FFI layer of PureScript, there is no question that it's nice to have validation, etc., but it's just not worth it.

The very restrictive view of packages (where to get them, what you can upload and use, etc.) is also a very obvious deal breaker.

I would be surprised that you find these two things that everyone keeps bringing up not to be good answers to your question, but then I remember how being in the Elm community felt like: "Everything Evan says or thinks we all think". It's the same culty feel that Elixir has a lighter version of.
