Whether the UK remains or leaves the single market isn't really relevant. Triggering Article 50 opens up the possibility of leaving the single market, but doesn't necessarily result in it. Triggering Article 50 is one of the simplest ways of leaving the EU, and it was almost universally agreed across both sides of the referendum campaign that Brexit (if that was to be the outcome) would be achieved through the triggering of Article 50. I don't think those who want to leave the EU are especially hung up on Article 50 -- it's just a means to an end. How the UK leaves the EU isn't vital. What's important is that the UK does leave. Those who oppose the triggering of Article 50 aren't doing so because they want another method of leaving the EU -- they don't want to leave at all! The question is ultimately about whether the UK should leave the EU or not. And the decision was already made on 23rd June.
