I think that, if you're a very small group, it would be hard to have a significant impact on this debate. We could go for, say, unanimous consent. The reason for not doing that is that, once there is one member who can hold things up, they then have a basis for log-rolling. Is that really what you want?
That's why I mentioned the liberum veto. If you want to just go and read about the liberum veto online, it was how the Polish parliament was run in the 17th and 18th centuries, and it was not a very effective way of running a government—I'll just say that.
