If you're successful with running tubeless without sealant you're still missing out on a big part of the tubeless value proposition.
Except that for some of us, the sealant is more of a liability than a benefit. I rarely get flats on my bikes with tubes. I certainly have never gotten a flat that I can remember on the dirt roads where I usually ride. What I do like to do is experiment with different tires and sealant makes that a royal PITA. Want to switch tires to try something out for a few rides? You're either trashing a bunch of sealant or trying to pour it from one tire to another and either way you're sure to have a mess to clean up afterwards. Tires need to be somewhat tubeless ready and hopefully agree with your tire/rim/rim tape combo or you're resorting to an air compressor to seat the bead. I wish I could ditch the sealant because since I have switched two bikes to tubeless, I have spent more time and money messing with sealant and other tubeless stuff than I ever have spent changing flats. I like the lighter weight and less rolling resistance of tubeless, but the sealant is what always makes me question the whole proposition.
