What can't you do? How is it any easier to audit minified JS than a WASM blob ? Everytime this argument is raised there is no valid argument to explain why WASM would be much worse than the current state of JS.
Minified JS (even with single letter variables and all) is still a high level language which is much easier for humans to follow than bytecode.
That was only an example of it being a valid concern.
I actually love WASM (specially the s-exp representation) and have implemented a compiler that compiles to it, but it's important to listen to valid concerns even if we really like a technology.
