>>33257661 (OP)Generally speaking they'll just haunt you over the years. Like oh you've found a job? Unless you're working illegally they'll start looking for a way to subtract something from it(if your country's labour laws allow you to demand being paid in cash that's the way to avoid it, also good for dodging child support btw), the different court orders will tank your credit scores, it may even reflect on things like insurance rates.
You can live like that if you own nothing to your name but you'll always be dependant for let's say a wife or mother who technically owns the property you're on, your relatives have to write wills where they exclude you but your share of inheritance goes to that proxy etc. etc.
Plus, obviously, if you can't control your debtmaxxing you'll end up being victim of more aggressive debt collecting tactics of some loan shark. By more aggressive I mean hire thugs to break his knees kind of aggressive.
