I suppose a lot of the fixed costs are lawyers charging $1000/hour to fill in some blanks on some Word templates?

Maybe an entrepreneur just needs to make that a web form. Fill in details and generate the same form for $10 instead of $1000.

And then some robots to print, seal up, and mail the envelopes and we're done.

I should be able to spin up a Dutch shell company like an EC2 instance. Maybe have "AWS" regions for Cayman and other places too and a Python API to spin up shell companies in arbitrary locales.
