It is possible to increase prices whenever demand outstrips supply. That's not really price gouging, it's just the market doing its job to decrease demand. At $6/gallon, fewer people will be buying gas. If the government artificially reduces that cost, the government (read: tax payers) are making up the difference somewhere else.
Government does not produce anything, so it cannot increase or decrease prices on anything, if it does so, it must do this by taking money from one pot and putting it in the other (robbing Peter to pay Paul).
Biden reversed a lot of the cybersecurity policies Trump had set in place. According to the gas line company, they had funds and were looking to hire a CISO (Chief Information Security Officer) until ~3 months ago, operating cost increases suddenly made this cost prohibitive and the DHS dropped those requirements. I wonder what happened ~3 months ago - oh right, Biden increased taxes and regulation on our aging oil and gas infrastructure in order to fund his pie-in-the-sky green new deal and reversed all Trump regulation because "orange man bad"
I work in IT security, the first post to start cutting cost is always IT security and regulation compliance. As the price of oil artificially increases through carbon taxes, we'll see a lot more of that.
