Without goop I think the chance of a pinchflat is much lower so you can ride with lower pressures for traction reasons or comfort. That is an advantage riding off road on a cross bike or MTB. Pinchflats on a roadbike is a no issue for me. My flats on the roadbike are almost exlusively caused by small glass pieces or chips of rocks. For that you need the goop to make the tubeless tire self sealant.
What about putting tire sealant into a tube before you flat? Isn't that what tire sealants are for?
With Schrader valves it's easy to put in tire sealant; with Presta valves it's easier if you have a removable valve core on the tube although it can be done with a non-removable valve core if the person putting in the tire sealant is careful.
The famous "Green Goop" sealant costs about $2.20 a wheel (Amazon) and
takes only a few minutes to install.
Green Goop apparently was originally concocted for the early off the
road bunch (late 1980's) and apparently is a success as it is still
Two Bucks a wheel (Plus tube) is certainly cheaper then a tubeless
tire and wheel will be :-)
