Theoretical question about how CD's work

The OP is clearly trying to make the point that if it’s all 1s and 0s on the CD how can anything make a difference - the data on the CD cannot be changed. Hel-loo! It’s not exactly rocket science. It’s the same argument regarding digital cables. They’re both Strawman Arguments. Can we please try to be a little more chill?

Since we've already gone pretty far down the rabbit hole I've got a related question. @almarg mentions EAC and FLAC. When I rip a CD to FLAC using db Poweramp what does the data on the FLAC file look like. Since it can be compared to a perfectly accurate copy (whatever that means) it shouldn't need the error correction wizardry. Is it just a stream of 0 and 1's or is it more like internet packets?

8th note
The Flac file is exactly like any other file, a bunch of 0s and 1s. It is a "non lossy" compressed format, meaning that its size is smaller than the original but no information is lost. BTW an internet packet again is a stream of 0s and 1s !!! 
I for one do not believe any error correction is needed. You copy a file you get a perfect copy unless someone can show me why a copy of a Data file from a CD should be different from a copy of an audio file.
Differences may and will come up when you "render" that file. I.e. when you get back to the analog world via a DAC; that might be slightly different (the rendering I mean) from one DAC to another resulting in a slightly difrernt analog signal. Same digital input, different analog output.

You need error correction because there are often errors when playing a CD in real time, which is quite different than simply making copies of a data file.
