illiquid wealth != unreal wealth.
as I said, if it were unreal you wouldn't mind losing it.
if it is illiquid, you clearly do.
economic illiteracy is not the best foundation for arguing against taxing the wealthy. by pretending the wealth "doesnt really exist" and "isnt there" to tax it highlights the underlying greed motivating the argument.
if you dont agree, perhaps elucidate on a more legitimate reason you might have had for confusing unreal with illiquid?
