It's not possible for a system that can communicate remotely to prevent tracking on some level by using unique IDs and fingerprinting even without JS. It's also not possible to have a programming language that can't also be used as a coin miner, it's just a CPU based operation and there's no way to discriminate between user desired computation and exploitative computation. Your point about pop up ads is valid in that JS does not need to be able to influence the state of the browser in that way, this is the only example that crosses outside of the sandbox.

I really, really want to see someone write a coin-miner using only HTML and CSS.

It's certainly possible.
