When you do get the tyre off there is a mess of sealant to contend with.
In addition, if the sealant fails to seal and you need to fit a tube, you'll have to do something about all of the thorns and flints in the tyre that did seal - if you don't, your tube won't last very long.
It's often stated that tubeless tyres have a lower rolling resistance (i.e. are faster) than regular tubed tyres. This isn't the case - adding the necessary sealant adds resistance just like adding an inner tube does.
