Security. WASM is sandboxed by design.

Many things are "sandboxed by design." Few things are true sandboxes.

I'm very skeptical of the idea of throwing out virtual memory and process isolation to depend instead only on software sandboxes.

That and performance. System calls have a lot of overhead when running in user space. You can dodge that when running as part of the kernel.
