Nobody is saying don't do it at all.... you are a grown up and part of thats involves taking resposibility for your oown decisions. Personally I would think very carefully about securing a loan on your parents house with no back up plan.
All WWW et al are trying to do is provide a bit of balance because coming out of training into the jaws of a potential UK/US recession with £80-100k of debt to repay and no-one recruiting is certainly a possibility.... what probability you assign to it is up to you.... weigh up the information at hand and fact that into your decisions making process be it modular/integrated/continue working/go full time etc etc.
