any mechanical movement will result in scratching grinding...

it's just how you see it and what tolerance you have...  from mechanical engineering point of view, any parts in contact motion will have scratching effect producing particles, in turn those particles will act as grinding agent to further the scratching process.  do you think nowadays this principle has vanished?

For some people they don't care, for example, car rental company.  they just want to rent the car out to make money even the car is new; when the car reaches 40kmi they will sell it.  the damage on moving parts in the first couple thousand miles nobody see it.  so they don't care.  this is one of the reasons you don't want to buy a rental company's car.  you are not a rental company, aren't you?

there are a lot of discussions on websites, google it you will have better understanding.  in addition to what you said - don't use cruise control in first couple thousands, don't drive on highway for extended distance, etc, you are encouraged to change oil at first 1000 miles (change oil filter as well), change it again at 3000.  after that you can change oil at regular intervals and driving normally.

car is yours whatever you want to do is up to you.
