The exit tax is not some wealth/estate tax that will make a huge dent in your assets, it's simply making capital gains tax due on the date of leaving US, not on the date of the sale of capital asset. It's extremely easy to pay zero exit tax when you leave US: just liquidate all your positions, so that you only own cash. This way, you'll just pay capital gains tax instead of exit tax. Of course, there's no reason to do that, because both are equal.
