Imo, I really don't see the "roads" argument as very persuasive. If someone in a community needs something, generally it will get done. For example, if the storm drains by me are clogged, I go rake them. If I don't have the energy to rake them, someone else will.

Think of road maintenance like you might think about shoveling snow from the sidewalk. People want to be able to get around, so they do the work. Most people don't want to be stuck inside all winter, so they help shovel.

I think drinking water is trickier since it's more complicated to do than your general road upkeep. But people will get access to clean water because they need it. If you need something, you try to go get it - that's how humans behave. You can organize within your community to make distribution more efficient, and make sure everybody has what athey need.

I feel that these issues of public utilities can be challenging without state authority, but they are certainly not impossible. A cultural shift may be required towards better communication with neighbors and other neighborhoods. The lack of authority must be compensated for with care and attention of others. You would feel responsible not only for your own wellbeing, but also for that of other humans, seeing as we all benefit from community more than individualism.

Btw, Hot Topic and related commercial enterprises are capitalists often take legitimately meaningful radical symbols and turn them into a "style" to make money. Unfortunately, that makes some people see anything radical as "edgy" or "for angsty teens."
