That’s not a disadvantage, that’s a feature. That the way it’s meant to work.
It’s precisely intended that if a party wants to spend all its its capital opposing, then it does that at the cost of being able to advance its own policies.
If it costs me two votes to oppose your legislation, but only one vote to introduce superseding legislation (which could supersede multiple of your legislative items), this seems like a much less stable system than today.
Chaos in law-making is probably worse than the disaster of two-party first-past-the-post.
