ELF binaries aren't executable either: They require the kernel to interpret them, preparing virtual memory and granting it a pid. Alone, they're just sequences of bytes.
What's your point? That you are willing to extend this principle to ELF binaries doesn't really affect my argument.
My point is that for the purpose of letting some non-trusted instructions run safely in a program, encoding them as JSON or Lua will come with the same caveats. Ultimately, they are both interpreted and can be sandboxed thus. Neither contain any code that will be passed off as-is for the CPU to execute. In some cases, neither does an ELF blob.
