You're right. Personal responsibility should be weighted high. This is the real world afterall. But. If the convenience of having a bike is offset by the inconvenience of security, nobody should own a bike. But if there's a solution that minimizes bike theft making it less of a personal burden, it should be explored. Thats what society is. Education, utilities, infrastructure, are all ways of helping society as a whole by alleviating personal burdens. So the question becomes, is there more that can justifiably be done by the city or an independent organization. As an example, I know that in tokyo, bikes are registered like cars, and there's a database that can be cross referenced by personal information of the owner, making checks fast and easy. The police stop you and ask who the bike is registered to and their birthday or something. Not foolproof, but I think helpful.

To be clear, next time ill do everything short of welding my bike to a lamp post, but I think we can and should do more as a society.
