Assuming you mean the distinction between moons in general and the Earth's Moon (Luna), if I wrote "neil armstrong was the first human to walk on the moon" would you think I meant anything other than Neil Armstrong walking on The Moon? Meaning doesn't go when the case changes in anything like the way meaning goes when the letters change. "neil armstrong was the first human to walk on the roof" is a very different sentence, you can't get anything like that difference with just case changes. If I spoke it, you wouldn't be able to tell if I spoke the correct case or not. Would you want school children searching for "one small step for man, one giant leap for mankind" and Google says "no results" because they used a lowercase m in mankind? Would you want a TV quiz show asking "What is Europa?" and a contenstant answers "a moon of jupiter" and the host asks "do you mean moon with a capital m or lowercase m?" before they decide whether the answer is correct?
