is there some perceived disadvantage to paying LT cap gains taxes today vs paying LT cap gains taxes at some unknown date in the future?
Maybe I'm dense.

Maybe you are just high income. The rate changes with total income, currently for a single person the LTCG rates are 0% for the first 47k, 15% for 47-518k and 20% above. It is good to cash some in on low income years.
