Earlier quoted context omitted.
Surely water is more strategically important than chips? It's just that chips are scarcer and thus easier to deny an enemy. If an enemy had the choice to deny one of the two resources, water would be the better strategic choice.
No way, if water gets really scarce, the price will go up, and two things will happen: 1. many frivolous uses will go away - swimming pools, spray-and-pray agricultural irrigation 2. new sources will become viable - like desalination Ultimately we live on a planet replete with water, it's just uneconomical to purify most of it for use at current rates. The same is not true of microchips.
At some point it becomes simpler to address this problem at the starting point rather than assuming the market will automatically fix any downstream issues.
