Yes. These are great reasons.
But it depends how big your DB is and how much data is being retrieved by the application at a time.
Most databases are not that big and the application does not need the whole database to calculate some number. If that's the case, then we do not require all these DB features. Using these just makes more trouble that it is trying to solve.
The DB I am talking about is not big and the application does not retrieve the whole database to make some really complex calculation. So getting rid of those views on views on views ... and moving to the application was a justifiable step to reduce complexity and blood boiling. Some disagree, yes. But that's how it is and it seems to work.
