I think this is true op.
I am glad you have sorted out a lifestyle that works for you but, given that you have, I still don't really understand why you would be driven to declare a blanket "rule" for blended families that you feel so certain is "the only way", and then make people vote on it.
It's not as if - on your posts - you are seeking guidance in good faith, but rather just wanting to assert you have it right and you want to have everyone say so.
My issue with this is that, while sometimes a blended family can work, it isn't easy because there are more than the normal family tensions, complications and conflicts of interest and far too many children end up in vulnerable circumstances as a result.
The thrust of your stance is to want to "enshrine" a pattern of behaviour that is fundamentally aimed at curtailing support - in this case financial - for the children involved. Of course sometimes that may work out fine, but it won't always.
I completely understand why posters might come with an open mind for advice if in a conflicted position, but you, on the contrary, have essentially said "Look everyone, I know exactly what I am doing, I will hear nothing else and just watch everyone say I am right. Yippee!!" These are often delicate situations and I don't know why you would bother wanting to assert such a blanket and unnuanced stance when you can't possibly have factored in the huge variety of nuances that exist in people's family circumstances.
