Yes but the point is you realise all this. And if it was important enough to you (v cost) then you would sort it. Most people wouldn't be interested at all.
Yes regulation and other stuff is sorely needed. But in the context of what an individual can do 10%-20% is nothing to be sniffed at. And I suspect that severely underestimates the savings compared to the average person, let alone the worst offenders.

If collectively it means 0.00000001% change I don't find it provides much "I did a good thing" value and the time would have been better spent fundraising, petitioning politicians, or maybe even just raising awareness towards say... improving a law that makes a collective 1% difference.
