Companies want to maximize profit and minimize cost, while customers want as much as possible for the lowest price.
Take covid inflation for example. Covid caused supply chain issues which then caused a temporary bout of inflation, however, companies took this as an opportunity to increase their profit margins more than they need to. They specifically bragged about this in quarterly earnings calls.
If companies truly compete on cost then how does stuff like that happen? Shouldn't it have been corrected by now? But that's not what we see, we see companies continue to increase prices with little consequence.
You're writing this from the comfort of your home where you're enjoying the fruits of the most significant quality of life improvements over 200 years. Hedonistic adaptation has blinded you to all of the evidence that's staring in the face, like the screen you're reading on right now.

Temporary aberrations from extreme disruptions do not refute the general rule.
IMHO, you can't have markets without regulations, and the markets that work best are those in high-trust societies, and that high-trust usually comes form a solid regulatory structure (i.e. laws).
This is why saying "deregulation is bad" is just as incoherent as saying "regulations are bad." We need to move beyond that sort of fallacious dichotomy.
Public goods and common goods need artificial markets created by regulatory frameworks.
Neither public services nor private enterprise is a silver bullet to everything.
They pivot or they slowly die.
Also quantitatively cutting costs qualitatively looks like enshittification of goods and services in practice, and unlike in undergrad economics textbooks consumers rarely have recourse in the form of switching brands since basically all "markets" for necessities are oligopolies (thanks often to government contracts for public works in an increasingly privatized world, if not simply the natural global minimum of any market).
On a basic level the point of putting a commodity on the market is to sell it to the highest bidder. Why is this the preferred way to distribute necessities? It certainly "aligns" with one particular incentive - that of the seller - not that of most people. Doesn't everyone need access to healthcare, housing, energy, etc.? Are poor people to compete with people who can outspend them several times over for food and housing? As the cost of living continues to increase does it make sense to hand over an increasing portion of our wages for the same - or worse - standard of living?
If you want freedom of choice in what you consume and have the means to do so then go ahead and turn to a market to buy a penthouse or gourmet food or whatever. But why is it such an offense to the current hegemonic ideology to ensure that there is basic universal access to essential resources?
