The problem is the only constant is change. Customer requirements are rarely static. So it's incredibly important to put thought into designing code that's also flexible and maintainable. Because what will happen is customer will inevitably thought of feature X or find bug Y and if they find out it takes a week to fix it, they won't be happy.

But I get what you say about doing those other things to make sure you don't run into the problem of changing requirements.

Part of the problem though is the varied skill level of developers and adequately timing the completion of these tasks. Most companies never budget appropriately for design and just expect banged out code. And there's not enough push back from developers on this, therefore it's become an expectation.
