Fully agree with you: the sealant was supposed to work. But unfortunately, it does not. I use good quality and expensive sealant – Schwalbe. The tubeless is rated as 6-9 bar and I use it at 6.5.
So, I must accept that tubeless solution is poorly developed for road bikes. There are lots of nice stories related to the sealant that silently seals the small cuts, but the reality proves that the high pressure in a road bike tire does not allow the sealant to permanently seal a cut. It is a good emergency solution, since the liquid flows out of the tire at a much lower rate than air, but you cannot ride forever with a continuous spray from your tire, clogging your mechanisms and dirtying your frame.
MTB experience might be different, due to lower tire pressure.
