There's another book where the KLF discuss burning the money, and that's one of the things mentioned.
A lot of people seem angry at them for burning the money instead of giving it to charity.
No one would be angry at them for spending it all on something dumb (e.g. a boat), and this way everyone else's money gets worth very slightly more.
Of course, they can just print a million pounds immediately upon learning someone destroyed a million pounds. So unfortunately that argument didn't actually work.
Also, the argument ignores the potential velocity of money - as a million pounds moves through the economy it creates economic activity that otherwise may not happen, even if they just buy a boat.
