No, not at all.

Yes at all. I think you misunderstand the significance of "general computing". The binary string 01101110 is a general-purpose computer, for example.

No, that's insane. Computing is a dynamic process. A static string is not a computer.

It may be insane, but it's also true.

Notice that the Rule 110 string picks out a machine, it is not itself the machine. To get computation out of it, you have to actually do computational work, i.e. compare current state, perform operations to generate subsequent state. This doesn't just automatically happen in some non-physical realm once the string is put to paper.
