Walmart can't print money & isn't going door to door to collect taxes from people. Without a govt to extract money from you corporations become powerless to extract anything without your voluntary participation.
Why are people so easily fooled into believing corporations are the root of the problem when the govt is so obvioisly the source of theft & abuse?
Is it all just Stockholm Syndrome?
I agree, although I think you'll agree with me that something like Walmart does not simply "happen" in a free market. It requires the State, especially the legislative branch, to help it happen. In exchange for whatever.
Walmart was origninally a free market creation, but yes its current size & lack of direct competition are the result of govt subsidies & protections.
Oh, absolutely. My thesis is that in a free market, with excellent business people at its helm, Walmart would be a large regional grocer in the US. Maybe.
To become the behemoth it is, though, its leadership must necessarily excel not at business, i.e., at providing consumers with what they want at the cost they want it, but at regulatory arbitrage. In the process, it coopted itself.
It's not by chance that most of the news stories involving megacorps like Walmart or Amazon are always political in nature, and so are the PR stories they spin out for public consumption, as a form to pressure politicians and regulators in their favor ("think about the jobs", "think about the taxes", etc)
Because they are taught
βCutting taxes and letting people keep more of their money is inflationary, but letting the government tax you more and then spend it, is not, because Government care about you and knows bestβ
"Price tag increases -> store makes pricetags -> store must be greedy" 
Do you think the government is more responsive to you, or to Walmart?
But I agree, corporations are not the root of the problem. But they are "corporate" entities, like the government, and are creations of the State and have special privileges.
I plan to read up some on Britain's East India Company and the Dutch East India Company, which were two armed corporations that behaved like states and had the backing of their governments.
As I'm sure you know, even the CIA has front companies it uses abroad as well as some in Silicon Valley, like InQTel, to carry out the government's nefarious deeds. I think we've entered a phase of fascism, in the sense of government coordinating with corporations ("public-private partnerships"), through entities like BlackRock, State Street and others, to push things like DEI, the LGBTQ agenda, transgenderism, COVID and the vaccines, censorship, surveillance, election manipulation, etc.
Using corporations, governments have been able to do things with less pushback than they would get if done outright by the government. All that said, I'm not against businesses, but I do oppose their capture by and collusion with the State.
But again, remove govt theft, subsidies, & monopoly protections from all of the above "corporate" entities & what do you have?
Govt violence is the primary source of all special privilege & predation. The thing that distinguishes a govt from a business or charity is forced funding.
The primary source of the problem always has been the government (in my point of view). The level culpability of those corporations is discussable
Walmart is a publicly traded company. Their method of printing money is issuing shares (most recently in 1969) or offering bonds (august 2023). But you're right that all interaction people have with Walmart is voluntary.
People are the problem and they run everything. Everyone is just running the grift they can - from harmlessly "borrowing" some office supplies to hooking your buds up with a billion in defence contracts. Its all networking in the end. Its bro deals all the way down...
