We haven't done it yet, but even if we had it's not a comparable analogy. We have a plan to get a few people to Mars that (while not exactly cheap) could conceivably happen. Similarly we already have lab-grown meat at very small scales, at a fairly high markup.

What would be a comparable analogy would be maintaining a stable, economically sustainable colony on Mars with similar population growth to what we might experience on Earth. Nobody has any remotely realistic proposal for how we are going to get there, just as no one has a remotely viable proposal for how to scale up current lab grown meat production to even an appreciable fraction of current meat consumption.
