I heard in the UK, public assistance is sometimes termed "job seeker's allowance."
Please be under no illusions about jobseeker's allowance. It's a tiny amount that you can't live on, for people who have no choice about being unemployed. The only way you could survive is by applying for a raft of supplementary allowances for housing, clothes etc, and even if you got them you would still be seriously struggling.
If you chose to leave your previous job, jobseeker's allowance probably wouldn't even start until 26 weeks had passed. Either way, your job search would be expected to me highly active, constant and not picky - you're required to take any job whatsoever that would take you, within a 90 minute commute - 90 minutes one way, that is. Your job search and applications are monitored online and in person every week or fortnight, you have to make a minimum number of applications each week and those applications are checked for authenticity and quality.
I think you should forget any glossy ideas about benefits in the UK. I'm not saying that just because it's frustrating to see it being referred to like this (I was on jobseeker's allowance for some time fairly recently and it was grim). I'm saying it because I see a lack of research and reality in almost everything you're saying here, not just about jobseeker's allowance.
If you want to move, then research it, plan it and go for it. Make it happen. If there are practical challenges, find a way to meet them. If you aren't able to do that then work on being able to say where you are, at least until you're in a better position (with savings, coping or whatever) to plan a move.
You pointed me to this thread because I said something about symbolic action in a different one. If there is any symbolic action going on here, in my opinion it's wishful thinking and that is not a powerful or positive message to put "out there".
You've used the phrase day dreams. Day dreams are fine if you're happy with day dream outcomes (everything is the same except when you can escape in your imagination). That might sound judgemental or flippant, but I don't mean it that way at all - it's how I lived for years and it worked for me for most of that time. It was helpful. Where the limitations are is in having day dreams and yet hoping that to some extent they can manifest without doing what's needed towards that.
