Nonnull references of course solve this problem.

The @disable attribute was invented for this purpose too:

struct Foo {
    int x;
    @disable this(this) {}
}
void main() {
    Foo f1;
    Foo f2 = f1;
}


That prints:
test.d(7): Error: struct test9.Foo is not copyable because it is annotated with @disable
