Are you guys totally incapable of looking ahead so much as two seconds and seeing the consequences of your actions?
Here’s your statement: “ No, I don’t think shutting down pipelines and halting drilling has much of any effect on current oil prices.” Do you not understand that getting oil out of the ground and to a refinery and to gas stations is a very expensive process that takes a lot of time and money to accomplish? Oil companies spend billions of dollars to first find the oil, then drill, then transport, it may take years to produce oil profitably in a given area. But it only takes a few seconds with a pen for a president to stop them dead in their tracks causing a multi billion dollar loss and loss of the time it took.
Biden campaigned on eliminating fossil fuels. He was going to continue the war Obama started against the fossil fuel companies and do everything he could to shut them down and make the production of fossil fuels prohibitively expensive. You Libs continually claim that shutting down keystone did nothing to reduce current supply or raise current prices. What it was was the opening salvo of Biden’s war against fossil fuel companies. On day one in office, It showed them exactly what Biden’s intentions were. Their every intention and plan to produce and transport FUTURE oil was immediately put in doubt. Why the hell would they continue future plans to find and drill knowing the ass bag in the White House could shut them down in a second?
Cautious?? Reluctant to produce at past levels?
Seriously? NONE OF THIS OCCURS TO YOU AS A HUGE REASON WHY CURRENT PRICES ARE HIGH? You can’t connect the dots here? 
I can’t ask often enough: WHAT THE HELL IS WRONG WITH YOU PEOPLE??
