No it is not, it was constructed to fit the laws of this world.
No, but it was created in such a way that it is optimal for expressing physical phenomena and it is our only way to do so.
Then I'd say that he most likely don't understand it qualitatively, he just think that they does. People have so many erroneous beliefs about things like physics, it takes a really long time to hammer them out and it is impossible to do that without the maths, words like acceleration and velocity have different meaning to different persons till you define it mathematically etc. I'd say that it is really rare for people to understand Newton's Laws qualitatively but it is really common to be able to express it quantitatively. People in general are a lot better at maths than they are at physics.
Also, no your view is far from delicate, I have the same opinion but got to the reverse conclusion.
Definitely agree on this comment.
One of the things mathematics is good at is if used correctly, it provides a good way to state the structure and behavior of particular things which include physical systems.
Because of this non-ambiguity it is usually a good way to really get all people to have a standardized interpretation and understanding of the so called physical systems. Not only that, because of the non-ambiguity it allows anyone to compare the reality of the system against the language of the theory and straight away anyone can tell if its outright wrong (whether in general or by a single anomaly) or whether it still stands against the specific tested situation.
On why physics is hard, one thing I have to add is to first think about the history of physics (this can very well apply to any science humankind has endeavored in building).
Our understanding of physics has come about by a very large number of people who are very smart and very dedicated through curious investigation to find out about their world. I think everyone has at least one curiosity about their world, but with physics it is certainly something that needs a fair amount of dedication, insight, and possibly some luck to raise the bar on understanding our universe.
Over time as things have become more well understood, other people have found ways to take and transform that into semester or year long courses that provide a very well condensed, concise, and engineered view of something that otherwise took hundreds of years to understand and develop.
With this said, it is not surprising that many people simply do not understand or "get it" straight away. When we taught the engineered, refined material we are very likely in our time as a student come across situations where we can't look at the material in a variety of perspectives (Feynman referred to this as 'Fragile Knowledge'). It usually takes someone that has been doing it for a decade or longer to know all of the intricacies of their subject which are often in some form at least, left out of curriculum.
So don't feel bad if you don't get it all straight away. Most people don't and even those who do go well in their coursework may find out later that their understanding was not as dense as they thought when they gain new insights, perspectives, and relationships in their working knowledge: most of us do when working on something for significant lengths of time.
