This is a quirk of the English language. If you go to tech support to ask, "How do you unlock this iPhone?", you're not typically expecting a literal response like, "I don't unlock it; the phone is not mine." The question they are actually asking is, "How is this done?"
This site isn't a polling place to collect random anecdotes as a way to build consensus among the participants, so it doesn't make sense to presume the author is asking how you resolve this issue literally — as in (for example) "How much do you make for a living?" When someone removes themselves from the first-person example, they are likely asking about the norms of societal convention generally. So "you" in this context typically means, "How do you all (2nd person plural) [do this thing, act this way, resolve this issue] as a convention of society?"
The proper way to express this is, "How does one do [x]?" This would remove all ambiguity, but it can also sound somewhat stilted in today's common vernacular.
Not all questions are about specific incidents someone wishes to overcome at the time of asking. There are plenty of questions one can ask about how things are done in polite society. So if a question isn't being asked in the first person (e.g. "what should I do in this situation?"), you should generally assume the answer should be generalized to social conventions — "How is one in society expected to do [this thing] generally?"
Such questions can also be helpful to folks who come after.
