What happens when you get a pinhole leak? Sure, with tubeless it won't instantly flat. But pressure will drop. If you're on a long ride, then you gotta air it up...again...and again.
Sealant is there to seal any pinhole leaks or leaks around the tubeless valve. Use it.
I've used 1 oz of Stan's sealant instead of the 2 oz. Seems to work fine. I generally split the difference and have 1.5 oz per tire.
