I think you mean Prop 71 instead of 107. I voted no on Prop 71. I like the idea in principle but didn't like the requirement to gather signatures from all districts.
Instead, i would have preferred to see a bill making it harder to pass amendments, moving it to 60% or something similar. That said, a lot of the progress the state has had would have failed under either requirement. Min wage increase, end of life, recreational pot, etc.
I have never said to myself "wow, we propose and pass a lot of amendments that should never have seen the ballot in the first place". And if we did, i want to see the ideas. Keep proposing easy and make them need more voter backing to pass.

My understanding is that 71 won't restrict propositions or ballot initiatives. I read 71 as specifically restricting future amendments.
