It's not that scaling is an objection, it's that scaling is a barrier. Supply chains today tend to depend on things we already know how to and are actively mass producing. To add a new paradigm-shifting stage in the chain, it needs to grow to sufficient scale, which requires funding and R&D, and the path there isn't always clear. In other words, it's not so much that we can't get there, so much as we don't know how.
