Earlier quoted context omitted.
For most people, owning 100% of a company making $1M/year would be preferable to owning 10% of a company making $1B. It's not just that money has decreasing marginal value. It's about what life you want to live. The ten percent life is... just not for everyone, and maybe not for anyone, which is why it needs to be incentivized so much to ever happen.
Owning 10% doesn't mean you're a peon. At 10% of a 1B company you probably have a good amount of autonomy. Some people take pride in creating products that are widely used + lots of jobs.
If you own anything, you're not a peon. However, owning 100% of something is simply a very different mindset than owning just 99% of something. In the former, you solely control you own destiny.
In the latter example, you're beholden or subject to others. Not necessarily bad, but a very different experience.
Kind of like long term dating versus getting married.
