If you are like me and rarely get a tubeless flat that you can't plug you can carry a spare tube that is much smaller than the wheel/tire size it's a spare for. It will save you bulk/weight and be cheap. A tube will expand a great deal so a 700x 38mm tube is fine for a 29er MTB as a spare or a 26er x 2.1" tube for a 29er.
I have given away my spare tube several times over the last few years, but never needed to install it on my bike. That's a lot nicer with a $5CAD tube than it would with a $50CAD bling tube.
