Norway has had this tax for decades, and done just fine.

I don't see any data that gives any useful indication about this there.

Norway isn't in the EU, and the EU doesn't have wealth taxes, so it doesn't seem awfully relevant.

Taxes are levied on economic activity. In capitalist systems the main economic activity is created by companies by direct tax on profits or direct tax on labor they buy (wages for the workers).

Count the number of companies created and grown in the last 20 years and see the trend. If it's going down your tax revenues will decrease. So indeed number of companies created is a very good proxy for future tax revenues.
