I disagree with your assessment that large organisations are beneficial.

We can see with our current crop of large organisations that they really struggle to create anything new; most of their new products or services were developed by a small organisation and then acquired. A lot of those products are then enshittified and badly managed because large organisation politics screws things up.

Large organisations are inefficient (everyone has stories of people in large organisations literally doing nothing all day). They are horrible to work for because of the politics. They mistreat their customers and their employees. Their executives tend to lose touch with reality, surround themselves with yes-folk and descend into authoritarian psychopathy.

My personal opinion is that we would be much, much, better off if we had fewer large organisations and more smaller organisations.
