I've always found the fine-tuned argument to be really strange. The universe has the emergent properties it has because of its basic properties. Of course! It couldn't be otherwise. So yes, the basic properties are necessary for certain emergent properties.
The question I would pose is, how do you know that emergent properties are impossible with other parameters? We can say that these emergent properties are impossible with different parameters, but by virtue of the first paragraph you should understand that that is an automatic assumption.
Maybe very different emergent properties could exist that we would have no way of thinking about or describing, and those would, naturally enough, be "fine-tuned" to their outcomes, by necessity.
So anything that is is fine-tuned to its outcomes by default.
Fine-tuning seems to me to explain nothing at all.
