How is allowing WebAssembly to use the network any less secure than allowing JavaScript to use the network?

Don't ask me :).
At least WASM will get DOM access (and hopefully access to similar web APIs) as soon as the GC is stable and usable.
Once GC is supported, WebAssembly code would be able to reference and access JavaScript, DOM, and general WebIDL-defined objects.

The issue here is the same-origin principle, which rules out most low-level networking (since you could just bring your own SOP-ignoring HTTP client).
Personally I think that enforcing the SOP at all cost (and even when no cookies or other authentication headers are injected by the browser) is misguided at this point and holding back modern webapps.

But you will be able to do network access though the fetch API, and fs access though its own API.
DOM is not enough for that. You almost certainly would like to be able to communicate with your backend ;)
Here is a list of the "usual" web APIs: https://developer.mozilla.org/en-US/docs/Web/API And everything that needs network access or access to local resources (file system in the worst case) will never happen to WASM because of security considerations.
