The unrealized value is notional, not actual. This is a very important distinction. The notional value is often not remotely realizable. In many cases, the realizable value can be a tiny fraction of the notional value.
Most laypeople grossly conflate notional and real value. Taxing notional value massively inflates the adverse impact of tax incidence on expected returns relative to people’s casual intuition based on the relative tax rates for realized and unrealized gains.
A tax on unrealized gains is in effect a way of laundering a steep tax rate so that it looks “small” and therefore reasonable to the unsophisticated.
