Yeah, that's the whole point. If you make it so a felon is essentially completely shut out from mainstream society, it will be really hard for them to not commit crime again, since they may not even be able to get a job or find a place to live. So in effect you just incentivize them being jailed again, which is bad for them and for all of society, since we have to pay for it.
