Because it takes constant work to keep the line tight. If it floats, it tends to stay up and out of your way. Any slack with a sinking rope and it will wrap around things on the bottom.
Also, for scuba, you definitely do not want to pull a float with a spool. You can use a spool to send up a marker in an emergency and then ascend up the spool line, but you don't want to try to tow a float in deep water, in a current while holding a spool.
