These are very much the reasons why the IDists have not been able to show it statistically improbable.
That's not my point. You have yet to show how it could be statistically probable.
Yet! That it hasn't been done does not equate to can't be done. In that respect it does not serve the anti-evolution faction. They have no more an idea of its probability than any.
Consider caterpillars. A caterpillar has no obvious resemblance to a butterfly. The disparity in engineering is huge. The caterpillar has no legs, properly speaking, certainly no wings, no proboscis. How did a species that did not undergo metamorphosis evolve into one that did? Pupating looks like something you do well or not at all: If you don’t turn into something practical at the end, you don’t get another chance.
Think about this. The ancestor of a modern caterpillar necessarily was something that could reproduce already. To get to be a butterfly-producing sort of organism, it would have to evolve silk-extruding organs, since they are what you make a cocoon with. OK, maybe it did this to tie leaves together, or maybe the beast resembled a tent-caterpillar. (Plausibility over evidence.) Then some mutation caused it to wrap itself experimentally in silk. (What mutation? Are we serious?) It then died, wrapped, because it had no machinery to cause it to undergo the fantastically complex transformation into a butterfly. Death is usually a discouragement to reproduction.
Tell me how the beast can gradually acquire, by accident, the capacity gradually to undergo all the formidably elaborate changes from worm to butterfly, so that each intermediate form is a practical organism that survives. If evolutionists cannot answer such questions, the theory fails.
Another example of Christian ethics in action; in this case 'Thou shalt not steal.' Riiiiight.
