Your question appears to be "what's the point"? Well, clearly there are lots of points - to pay bills etc. when retired, to supplement the meagre state pension we receive, if in fact this is still payable by the time most of us hit that age, to enjoy retirement and take long holidays, buy stuff you want, the obvious really.
Sorry to hear your friend may not now be able to keep his money for that, but if this hadn't happened to him then I am sure that is the sort of thing he would have used it for her.
Also, as its a temporary setback then hopefully it shouldn't be too much of a problem for him. When he was made unemployed was he not entitled to any kind of redundancy pay-out?
