They're not actually no-cost, it's just that the costs are indirect so it's easy to lose track of them. For example, I'd be interested to see someone make and use a digital copy without a computer and electricity, both of which cost money. Distribution takes an Internet connection and servers, which cost money too.
The raw resources for bottles are abundant, but it requires labor to make and transport them. Labor is not free, so bottled water remains scarce. If robot swarms will refill and restock bottles for you, then you can take one off a shelf.

None of those come out of the pocket of the person being copied. I guess I was too unclear about specifying made by someone else. When we're talking about a '''theft''' scenario, the burden imposed on the person being '''stolen''' from is very important, and when it comes to digital copies they are uninvolved in the action and have no costs at all.
When you take a bottle of water, the cost of inventory (which captures the entirety of the amortized cost of production) is less than half of the harm to the shop keeper, because the markup on bottled water is well over 50%. The primary harm is the revenue the shop keeper will forego because he cannot sell that bottle.
In the digital realm, using a copyrighted piece of content without permission causes the copyright owner--who did have to invest in the original creation--to forego revenue as well.
