For example, there could be institutions of higher learning that required applicants to demonstrate evidence of having been cancelled. Such institutions might be more effective at producing novel and useful scientific ideas (as opposed to theories of biological sex, for example).
I wonder if there should be an age limit for being cancelled. If a 10 year old dresses as Thomas Jefferson for a school Halloween event, it might be good to give them a pass until they are 18 when they can make a better informed choice about whether they want to join the cancel culture or the resistance.
Unfortunately, this type of record keeping is typical exactly of the cancel culture I'm so opposed to.
In Brave New World, all the Alpha citizens were sent to an island. Within six years they had a full scale civil war. I suspect something similar would happen if you put those cancelled for voicing their second wave feminism in a way which offended people as a threat in a faculty with those cancelled for voicing arguments considered sexist, those cancelled for making arguments considered Islamophobic with those cancelled for interpretations of the Quran considered extreme etc.
Maybe you were religious and voted against gay marriage in the past. Maybe you used a politically incorrect term on Twitter. Maybe you donated some money to the wrong political party. Maybe you just didn't kowtow to the mob's latest demands. All of these things can ignite the capricious maelstrom of the mob, and once you are a target, they will pursue you with righteous indignation until you are "cancelled"
