Tamalam: Do we really think he won't stoop so low as to claim to be incapacitated and unable to work...
He would need to fall quite far to reach the point where a disability check would be his best option. He would be better off living in Croatia with a handful of Patreon/YouTube dollars coming in, than in the UK under government assistance.
I'm betting that, if it comes down to putting in more time/effort into making videos versus spending 30-40 hours a week slaving under someone else for poverty-level wages, he will suddenly rediscover how easy it is to make videos by himself. And he wouldn't need all that much support to surpass what he would get from a menial job in Croatia. The problem would be keeping/growing such a small support base a second time, without the help of the people who made it possible before.
