Umm. Maybe explain how that's supposed to work...

A TM has no idea whether it is being run directly or being run in a UTM. And even if it is being run in a UTM, it certainly does NOT have access to the machine description which is present on the UTM's tape.

How exactly is it supposed to know that? Please explain using ACTUAL Turing Machines, not C code.

It simply needs to know its own machine address.
And How does it do that.It is typically understood that a a simulated Turing machineand knows where it is located on the UTM tape.>
And how exactly would it have access to that? A TM emulated by a UTM has no access to the UTM's tape.

not the same as an analytical impossibility.
We never did it this way before therefore it is impossibleAssuming things that are definitionally impossible is a good way to show that you logic is just a LIE.
is not the way that reality actually works.
Which shows you don't know what "isomorphic" means.They are essentially isomorphic to x86 emulators.>There's lots of examples of UTMs available on the web. Maybe you should actually try playing around with some of them so you can learn how actual UTMs work. Hint: It's not how you think.
Once again, you should head the above advice. Apparently you have no clue how actual UTMs work.
