I would believe this if you had started fighting existing property taxes first and waited until you have finished that job before trying to prevent non-existent asset taxation.
> I dont expect normal people to have to sell their stock.
Selling stock isn't abnormal, it's done every day. More importantly, people don't have to sell stocks to pay taxes, instead they could use dividends or part of the income they normally use for buying more stocks. The current obsession with growth stocks is part of the problem.
> Capital Gain Tax should just be Income tax.
I wish a good economy could be built without any asset/property taxes but I don't think that's possible. As with everything else, asset taxes can be quite harmful if implemented the wrong way, but that's a different conversation.
