Rant: The "Dont pump gas" shenanigans

We have all received emails, communiqués, and memos proposing to the general public not to fill up gas for an entire day.
Recently, I saw a group on Facebook suggesting public action on May 15, 2007 along the same lines, and it struck a few chords for me:
1) "Crap", in reaction to the tainting of facebook with crap.
2) "This is absurd", in reaction to the idea in general.

I have always been cynical about actions like this, because according to my analysis, it is theoretically akin to pissing in front of Niagara falls.

For my argument, I present a base point, and a corollary to that.
Moneys earned, paid, and ultimately accounted are generally done so on a month-to-month basis. Thus, in order to affect any industry, an action needs to have a net impact on the monthly flow of funds.

Now, in order to maintain present lifestyles, Americans and Canadians owning cars will need to fill up sometime during the month. Thus, if all car owners were to avoid filling up gas for a specified day, the net loss that producers will see on that day will equate to a net gain of sometime the week before, or the week after.

Thus, the net impact of the month by not filling up for the day amounts to nil.
If it's an excercise in futility you seek, go throw a twig in a raging bonfire. At least you get to watch it burn.

Furthermore, given the number of players involved in gas prices (retailers, governments, producers, refineries, international business-people, the stability of countries that have, host, or are involved in the production of oil, etc), it seems rather unfeasible that a price change would occur the day after a public action (a common claim of the instigators).

Either the instigators assume the players of this industry are stupid, or they assume the majority of the public is.
Judging by the popularity of these antics, they're probably right about the latter.
