Actually not. If it is "necessary" then it is logically part of the sufficiency that you deny it having.
The fact that oxygen is necessary but not sufficient to form water does not negate the fact that oxygen is part of the sufficiency used to make water.

Yup precisely

Yup it could be designed and of course there is "no way of telling" because It also isn't showing a "property which we know "(ONLY)" come from intelligence." It shows nothing but properties that can be readily understood as arising from natural causes which are sufficient to explain its arrangement. Thus we apply Ockham's razor. You know how the razor is applied right?
It is a principle urging one to select from among competing hypotheses that which makes the fewest assumptions and thereby offers the simplest explanation of the effect.

I am also quite fond of Newton;
"We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. Therefore, to the same natural effects we must, so far as possible, assign the same causes."

Talking to me in the third person? and attributing me with an assertion I never said. Hmmmm this does not bode well.
ID is asserting that a certain property is a type of "information produced when intelligent agents act.". I am quite positive that they and I are also certain that such a property has not been observed to be caused by anything other than intelligence. In my empirical mind if I can find a natural cause for an effect then there is no logic to assume any other causes. I am reminded of a joke that seems to apply here.
Why is a lost item always found in the last place you look......
Obviously one does not keep looking when it is found. Tell me in your experience what have you seen that can create a mechanical motor out of complexly arranged matter that has many levels of complex interactions? What is sufficient to explain such a formation?.

Of course you don't see how. Most people don't understand how the big thing under the hood funtions and they use them every day like its some simple little thing made of plasm... It requires an understanding of mechanics and why things made of matter must be arranged in certain ways to gain a function before understanding can play a part in deduction.
The other thing you don't see nor understand is what the definition of ID is saying to you.
"4) Such research is conducted by observing the types of information produced when intelligent agents act."
Making something look naturally made is only one type of information that can be produced by ID. This is not its only type. Notice the five letter word "types". It's a neat little english word that implies multiplicity.
"Scientists then seek to find objects which have those same types of informational properties which we commonly know come from intelligence."
Now when a real smart scientist type person begin to look for other things in the environment he is looking for something that exhibits "those same types of informational properties which we commonly know come from intelligence". You see that neat little word is used again "types" and they even make sure you understand that the properties they base their inferences on are the ones "which we commonly know come from intelligence". Of note here is the implication that it would also be commonly known not to come from any other known cause.
