Agreed.

Phrasing the issue as latex as a "cleaner alternative" to tubeless is utterly ridiculous for a number of reasons, not the least of which is that it misses the point of running either option.

Physical disabilities and bad decision-making aside, dealing with sealant is not yucky nor messy (and by 'dealing with' I mean installing, using, removing, cleaning up, etc.).

I've been running road tubeless for three years, and I've never done anything other than run a rag around a rim to clean one up. I have pulled, plucked and peeled dried sealant from the inside of a tire casing, but that's me being particular, not a matter of necessity. I've had sealant spray on the back side of the seat tube, but it just rubs off with hand friction. Sealant, if you were to get it anywhere else, e.g. on hands, the floor, on the side of the rim, clothes, just wipes off.

Have the right tools for the job, including some rags, and you'll be good.
