I've never claimed JSA although I've been on benefits for years. I've always thought of the dole as just being JSA. I've claimed income support, PIP, carers allowance, DLA, housing benefit, tax credits, and council tax support at different times, due to being a lone parent and/or carer, but I've never had to show evidence of jobseeking, because it's not a requirement for any of those benefits. I don't feel guilty for claiming anything - it's just something I expect as part of living in a civilised society that looks after the disabled and families in poverty. If my circumstances were different I'd have no problem in paying taxes to support people who needed benefits to survive.
Our benefits add up to significantly more than £70pw, as it costs more to live with a disability and to raise children, and I think that's fair enough. Also, it's not just a short term situation for us - the disabilities in our family are incurable, so we need more money than people who just need a stop gap to tide them over between jobs.
I think all benefits should be there for anyone who meets the criteria at the time. I know many people who have struggled to find work for years at a time, and if they need support for that long, then they should have it.
