I get what you're saying, but limited liability has been a thing for quite a while now. It would be hard to find a few billion dollars to make a new car plant if you could lose more than you put in. But also there are already "piercing the veil" laws where you actually are liable for your business if you commit fraud.

Perhaps it's worth a rethink, as it's been a while since the 1800s when capital was scarce.
