Personally, I think the truth lies in the middle. I think having full history for purchasing coffee is not only wasteful of space clogs the blockchain (imagine 6 billion people adding 3 coffees a day to the block chain over 50 years). My back account keep track of all transactions for a few years and I’ve rarely needed more, but I absolutely do need a transaction history for budgeting and taxes. So a hybrid approach where important or big ticket items have full transaction history (until you ask to prune to a MW), and smaller ticket items can be in smaller MW subaccounts of different categories is the best of all worlds.
