Actually it's not true that local-first software cannot be businesses (or non-profit orgs but still revenue-generating), it's just that the money to be made in local-first is an order of magnitude (at least) smaller than with cloud software. On one hand, the money to be made is much smaller, but on the other hand, local-first is where the next big disruptions can happen, while still having a non-zero revenue. Look at open source or open data projects for some examples on this: Wikipedia, VideoLAN (VLC), OpenStreetMaps, etc.
