For any ride under 2 hours, I'm usually chamois-free as well. I have been forced into longer rides without one due to various circumstances, and it's never worked out badly. MTB is unique in that we spend a lot of time out of the saddle. If you're sitting and spinning for longer periods (road, gravel, and \*gasp\* e-mtb) the ratio of time in saddle to total time riding closes in, which could change things a bit, but I've also done long road rides without a chamois and - as long as you wear good underwear as Andrew described - it works out well.
