Making them continuous means requiring everyone to use a computer to calculate simple things like income taxes. Brackets aren't even a case of perverse discontinuities because the higher tax rate only applies to the money made in that bracket. Looking at just income taxes you never take home less money from getting paid more, it's a quite reasonable balance between computational simplicity and a rational progressive tax structure.
