Saving money is already discouraged by inflation. A wealth tax would be functionally equivalent to a fixed inflation rate, just the numerical values would be different.
Since the numbers would be going down instead of the increasing money supply devaluing savings, I guess people wouldn't like it, because losing wealth would actually feel like losing wealth.
