I think the height of taxation makes the difference. Your 10% would go up if the tax is higher. IMHO (or call it a gut feeling) the best way to ruin market value is not higher or lower taxation. You have to change the tax often and dramatically. Tie it to the difference between highest and lowest temperatures measured in the previous year every 13th full moon.
