'the publishing will only happen now' is the kind of assumption that ends up being false very rapidly. Or immediately, if you're writing automated tests. That's kind of the point.

I tend to write stuff similar to your example in C# (though I tend to make them 'public readonly' instead, because I hate accessors), and I agree that it's kind of tiresome. But that is really just a deficiency in C# - it lacks a concise way to express such patterns.

And to be fair, it's absolutely true that if you wanted you could just use global variables. You are absolutely paying an up-front cost when you do this, but you should look at that cost as an investment: In the long run it will pay off by making your code easier to understand, easier to maintain, and easier to extend, because its dependencies on global state are painfully obvious. Sometimes that investment may not be worth it, so you have to make the judgement call.
