For what it's worth, Windows 10 can be installed without the TPM/Bitlocker chip. Windows 11 requires it but there is a workaround available for older systems that do not have the TPM available on their motherboards. As far as those who are asking for Windows 7 compatibility, Windows 7 was the last OS from Microsoft that actually worked out of the box. Neither 10 nor 11 can lay claim to that.
There are still Windows 10 32-bit installations out there, though, which can run on 4-8GB of memory. Will run slower than a snail on an expressway, but it is possible. But purchasing a $90USD computer just so it is Win11 compatible? Why bother, as everything running on it will take too much time to be efficient. The "minimum" hardware requirements for Windows 11 is technically 4GB of RAM, 2GB of video and 10GB of hard drive but maintaining that system is more effort than it is worth.
No, thanks to the COVID Pandemic, the prices of computer parts have gone through the roof and what used to be fairly inexpensive in building your own computer has come to "modern," up-to-date video cards costing more than an actual computer does. An 8GB DDR5 video card can cost over $1,000USD brand new, a newer chip can cost several thousand by themselves without a cooler. You can look at spending close to $5,000 minimum to have a modern enough system to keep up with others but if you can build a computer yourself, you can customize it to how you want it, not the way a mass manufacturer builds it for you.
I can build computers from the bottom up, I fix them for a living. There are ways you can save money by building your own system but I can certainly understand those who don't want to be bothered, so you pay someone else to build a system for you. Whatever works for you is fine but don't expect the modern day era to accommodate those who have been left behind.
