Twitter

 Perhaps Elon Musk could turn Twitter into a force for good.

He could hire a team of social scientists, philosophers and lawyers to draft a code of ethics, or a constitution, with the aim or turning Twitter into a virtual country.

Users pay to be members, thereby generating immediate taxes, or revenue. With 395.6m users, quite a bit of revenue could be collected.

Any profits above the running costs (plus a bit of a bung for Musk to recoup his investment) could be devoted to good causes, such as Climate Change or alleviating poverty in the poorest countries/

Of course, any country (virtual or otherwise) has a duty to protect its citizens.

Naturally, it would be an autocracy but, as Musk came up with the funds, that's only natural and better than it being the Wild West.
