You make the law whatever you want and those become the terms. Either agree to them or you're not allowed to operate a business here. That's how taxation and other regulation work. You're free to operate a business in another country if you don't like it, just as an employee is free to look for work elsewhere.

The disagreement is whether a founder who owns 20% of a company that grows from $1M to $100B should personally receive $20B of the resulting value while thousands of employees and customers contributed to creating that value.

That's the debate.

If I pay a plumber to fix a pipe in my house, and the value of my house is assessed now to be higher, I neither owe the plumber any more than the agreed rate for the pipe fix service nor equity in the house. If I owned 100% (or 20% per your company example) before, then I still own 100%. If the plumber was already a shareholder, then he will reap the additional reward.

Any asset value can grow or shrink thanks to effects from people, such as paid services, but I don't lose equity on property/companies I don't own if I vandalize them, just like I don't gain equity when I raise their value somehow.

Employees of a company are just contracted service providers with longer duration contracts, and of the company is public, they are free to buy some of that risk and gain or lose more when the company does so. 20% of $100B is $20B, so there is no need for a debate, math has our back.
