1 - Regulation. You can do ICOs and Token Sales legally. If your tokens are not securities, you can do ICOs open to everyone. If your tokens are considered securities, you can do so on Coinlist.
2 - Tokens natively track the value of the network. For these networks, its value is not tracked by company shares. Ethereum is a good example of this. Ethereum Foundation is a non-profit and all the value accrues to the token. You can also do a hybrid system or none. Depends on your specific use case.
3 - Funding. Internet Bug Bounty is a good example of this https://internetbugbounty.org/. If TCP/IP would have been able to capture a billionth of a cent for every request things it wouldn;t be needed. Maybe, our infrastructure would be really different today.
