Step-by-step explanation:
a. One issue is the "locking-in" of assets. If I hold shares of Corporation X, then I can delay paying taxes as long as I don't sell. Effectively, I get to keep all of the interest/dividend payments on my tax liability. However, if I discover that X is really a poor investment and Corporation Y is better, then selling X and buying Y means that I have to pay taxes. This might discourage me from making a switch to a more profitable/efficient investment decision. This is the "locking-in" effect.
b. A short-run cut might cause many people to sell stocks that they had felt "locked-in" with. The penalty for switching is smaller, so more people will do it -- resulting in a great deal of cap gains tax revenue collected.
c. Taxing realized gains, even when the stock is not sold, rather than just accrued gains would eliminate this locking-in effect. Investors would not be penalized for switching to a better investment, and long-term capital gains revenue (as well as efficiency) would rise.
