That's kind of a simplistic approach, especially when it applies to the countless people who have been "cancelled" who aren't rich and famous, and also haven't done anything wrong except being accused of doing or saying something the mob doesn't like.

In your example, cancellation is not "the consequences", jail is, because that's what we do in a society of laws. In many, many cases cancellation is a grotesquely disproportionate punishment in the form of mass social shaming, sometimes to the point that an innocent person's life is completely ruined (job lost, harassed day and night with death threats, name forever associated with thousands of vicious social media posts and news articles). The key isn't whether you think they deserve it or not, it's that the mob assumes everyone is automatically guilty. Ordinary people get "cancelled" daily over a video of an encounter taken out of context and posted online, or by a simple accusation from a vindictive party, that gets massively amplified by social media, without any opportunity to respond or defend themselves.

The mob enjoys its moment of cathartic """"justice"""" of totally destroying someone's life for a few hours, the media get their clicks and views, and then they all just move on to the next target, while that person spends the rest of their life (if they don't kill themselves) putting trying to put the pieces back together. Is that the kind of justice we should condone every time someone does (or is accused of doing) something the mob doesn't like?
