That’s already why people buy apple and AppleCare.
What you are describing is taking this even further in the direction of an information appliance.
I am unconvinced that there is any benefit that your model provides that Apple does not already.
You can already just buy a Mac with AppleCare and install MS office from the App Store.
People may want their choices to be simplified, but they are also going to need to be able to use whatever important new thing comes along. E.g. Zoom or Slack.
If think more people would buy a subscription instead of forking out few grand at once. It will be like a finance instead you won't own the laptop.
I also understand this is quite stupid, but I feel that this is the direction Apple is going to go to extract even more money from their target audience.
