If you are concerned about running a tubeless tire with a plug in it, it can be done. Not necessarily recommended but a lot of people do it. Tubeless tires are usually very easy to fix on the road. I always carry a plug kit and co2 bottles. This is really designed to get you to a place where the tire can be repaired properly from the inside with a proper plug/patch. There are some sophisticated repair plugs that do just as good a job with a "button style plug" without having to remove the tire, as removing the tire and patching from the inside.
