So instead of a common tube, I'm carrying sealant, valve cores/tools, syringe? Pass.
Nope, as you don't need any of that stuff. Small holes will be sealed by the sealant, large holes you fix using a tubeless repair kit:
Which looks massive in that picture but is actually very small.
You stop, shove the pointy thing in through the hole, pull the device back out leaving the sticky rubber bung in the hole, then pump the tyre up again and you're on your way.
Bit of superglue on the cut, pump tyre back up. I've also seen someone stuff a bit of latex glove into a cut, melt it with a lighter and then reinflate.
If you do need to remount the tyre for some reason, presumably you'll have CO2
