No tubeless set up is designed to be run without sealant. It's not recommended, won't gain you anything, and will nullify one of the main reasons people run tubeless in the first place, puncture protection.
Ummm...no. The original UST spec does not use sealants. Many tire makers recommend NOT using sealant. A good UST tubeless tire will loose pressure slowly when punctured by thorns (been there). I have never needed to fix a flat of a dry tubeless tire on the trail because of a puncture.

READY tires are designed to be used with sealants, but the puncture protection is still secondary to just sealing the casing to hold pressure.
The main reason I use tubeless is the ease of swapping tires without needing to worry with inner tubes or mess with sealants.
Bonty TLR tires are designed to be used with sealant, though I have found the Abrasion Resistance Casing versions to be good without in most cases. They are also designed to be used tubeless only on TLR or UST-spec rims, which the Stans rims are not.
