If you're willing to live on a rather low budget and spend a bunch of energy gaming the system, yes, but that low of an income tends to stress most people out (especially since the system is known to do "fun" stuff like noticing that your insurance company compensated you for your bike getting stolen, and then count the insurance claim as income to be directly subtracted from your welfare payments).
Similarly, as rsaarelm mentioned, if you do anything that the system might consider "work" (sometimes including stuff like volunteering at an event for no pay), you might be denied your payments.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
