No, you are wrong.
Firstly, a "charging pad" requires a flat surface to be on. Meaning tables, desks, nightstands, etc. Standalone lightning cables do not.
A "charging pad" would also require the iPhone to be lying on it at all times. Personally, I prefer to be able to charge my iPhone and use it at the same time. Next to my bed for example, I have a long lightning cable that I use to charge the phone while using it. With a charging pad, this would no longer be possible.
So this "wireless charging" doesn't grant you any freedom of movement at all. In fact, it restricts it.
Lastly, I have several lightning cables plugged in around the house. Why would it be better to have to buy several "charging pads" in their place?
