sorry but no. If you want to claim job seekers allowance, then (as above) you actually have to be looking for work, which you clarly arent. TBH it makes a mockery of those of us who also work to pay for things whho also struggle to make ends meet that you want me to support you because you don't want to work in a job with more hours or find a different job. If you can afford to work low hours then great, but dont expect me to help pay for your food/bills when you could work more but simply dont.
I see your point about how the hours will go up, but what if they dont? or what if you suddenly decide its nicer having the time to yourself, and the taxpayer paying you instead of tesco?
