Gas boycott

I keep getting this e-mail about a gas boycott. The goal is to get everyone in the country to refuse to buy gas on May 19. The e-mail says

"IT HAS BEEN CALCULATED THAT IF EVERYONE IN THE UNITED STATES DID NOT PURCHASE A DROP OF GASOLINE FOR ONE DAY AND ALL AT THE SAME TIME, THE OIL COMPANIES WOULD CHOKE ON THEIR STOCKPILES. AT THE SAME TIME IT WOULD HIT THE ENTIRE INDUSTRY WITH A NET LOSS OF OVER 4.6 BILLION DOLLARS WHICH AFFECTS THE BOTTOM LINES OF THE OIL COMPANIES."

It then calls for the May 19 boycott and goes on to say:

"WAITING ON THIS ADMINISTRATION TO STEP IN AND CONTROL THE PRICES IS NOT GOING TO HAPPEN. WHAT HAPPENED TO THE REDUCTION AND CONTROL IN PRICES THAT THE ARAB NATIONS PROMISED TWO WEEKS AGO?"

So, here are my questions about this:
1. Who did these calculations, and what, exactly, are they?
2. How does a net loss of 4.6 billion dollars translate into cheaper gas prices?
3. Will it really work? It seems to me like it will make absolutely no difference if everyone just goes to the pump on May 20 and buys the gas they didn't buy the day before. If NOT buying one day would cause a glut, wouldn't EVERYONE buying the next day relieve it? Maybe this is oversimplification, but that's how it seems to me. If we really want to buy less gas, we have to be willing to DRIVE LESS and therefore, use less gas as a LIFESTYLE, rather than just do a one day thing. (But that is not the convenient, comfortable, quick-fix kind of answer we Americans like to commit ourselves to.)
4. Waiting for our administration to control prices? WHY? Is that really the job of government? I am so sick of the attitude people have that they can just blame the government whenever something goes wrong and expect them to fix it without ever having to PERSONALLY do anything more than a one-day boycott.

Whatever. If I need gas on May 19, I'm buying it.
