I ride very simple bikes of very easy terrain and it is very black and white for me. I don't find myself making compromises let alone endless compromises and balancing acts.
You do make compromises and you are already balancing your needs, even if you don't realise it. You've found the optimum tool for your use case, but you could still go lighter again, I very much doubt you're at the limit of lightness.
The point is, as you have already acknowledged, your current riding is served adequately by your current equipment, and if your riding is consistent then your needs don't vary much.
If on the other hand your riding is extremely varied you have to make more compromises (or keep changing bikes mid ride!). One of your requirements is the feeling of a light bike, as it's important to you, it's also important to me, but not at the expense of other performance metrics.
If you moved or your riding changed you might have to compromise, either by changing your kit, or if the feel of your bike is more important to you, then by riding differently.
ie: I could use lighter wheels or tyres, but I'd end up walking home more often, so I compromise. Just because you've already reached your compromise doesn't mean you haven't made them, or balanced your needs already.
Weight may be important, for some it might be the most important factor, for others it might be further down the list, doesn't make either of those people right or wrong, it just means they have different requirements.
