For those who have a genetic predisposition, you may be right. You may get type 2 regardless of what you do.
But the majority of today's type 2 is obesity generated i.e. overeating and under exercising.
The modern lifestyle is all about ease and convenience (i.e. less physical exertion) and food choices EVERYWHERE and all around you, even delivered to you so you don't have to walk to your car to go get it.
