It fascinates me to see how these regulations give rise to market-based workarounds. I’ve elsewhere called this the speak-easy economy. The government bans something. No one likes the ban. People are determined to get on with their lives, regardless. They step outside the narrow bounds of the law.Maybe you can't stop the signal, but you can sure muck it up.
It wouldn’t surprise me to find, for example, a sudden proliferation of heavy-duty “water cans” in 1- and 5-gallon sizes, complete with nice spouts and vents, looking almost exactly like the gas cans you could get anywhere just a few years ago. How very interesting to discover this.
And yes, speaking as somebody who uses gas cans a lot, the new designs have probably cost me hours in total, just filling the Jeep. Safety-wise, it's not an improvement. But as a way of keeping how important the government is right in my face at all times, it works like a charm.
