I think the point is that if you think you have a chance of accumulating wealth (either through founding a start up, or from stock grants from an established tech company), and you have an option of living in a place with a wealth tax or one without a wealth tax, you will very likely choose to live in a place without a wealth tax. Your right, it is a lottery ticket, but if you are going to buy a really expensive lottery ticket, most people won't want to give up a large chunk of the value of that lottery ticket, so they'll start businesses elsewhere. Whereas some people think the government should tax wealth, this shows that governments are likely to have less tax revenue as people move out of that state/country. Given the recent shift to more remote working, this means that people are less tied to living in a particular place in order to have a certain job.
