So tax them as much as needed, or require state ownership of some amount. Startups, and company entities in general, exist because a jurisdiction allows them to, or allows them to accept payments, control accounts with financial resources, pay vendors and workers, and operate within a commercial framework. That is a privilege, not a right. The rules are a shared agreement and delusion, the rules can change at any time.

Actually participating in commerce is considered a pillar in defining a liberal democracy, in the words of John Locke, so I would say that is a right.
