Where to start?
Meta isn't for complaints really. It's for discussion, feature requests and questions about the site. This isn't a question or topic of discussion really, but a very localized case of your own issues coupled with some bit of misunderstanding of site practices and policies - asking about the policies rather than begrudging things that have happened is a better way to approach such a problem. In this case, asking in chat would have been a much quicker way to resolve your confusion about these practices. Regardless, as the editors didn't explicitly tell you what was going on with their changes and, as you seem to be new, this may have led to your confusion. I would always recommend doing some research into policies and practices before complaining, but I'll explain to you the reasoning I see behind those changes, hoping that it helps clear up some of the confusion.
I'll start here, since this is simpler to explain and less subjective.
Firstly, the "flags" as you call them are called tags (it even says it up a at the top of the site - I just checked) :P. Silliness aside and assuming you knew that, the tag changes were valid and in line with site tagging policy.
As addressed in this meta discussion, the proper usage of platform tags is for questions which are clearly about interactions with the platforms themselves. The tag description for the pc tag says "The PC tag pertains questions about PC-specific problems with a game, and the tuning of a PC configuration to best accomodate gaming." Your question does not relate to the PC in any way but relates solely to the gameplay and strategy as applied to one specific game. The platform provides no relevant information to your question. Admittedly, if console commands were of concern to this case (they aren't), the correct answer might include them and there is nothing in your question which precludes the inclusion of console commands.
Series tags are for questions that relate to the series. The tag description for the-elder-scrolls clearly states "Questions about Bethesda's award-winning "Elder Scrolls" series of games, either for questions that span multiple games, or for lore questions outside the scope of individual games." Another scope in which your question was not as your question was only about the one game and has nothing which extends beyond that one game.
This is more subjective.
The site is meant to be useful to many users in the general public. I'm not sure what "cruft" is as the user who made the edit described the removed content, but much (not all) of the content removed did not contribute significantly to your question as it was and made it harder for those looking at your question to know what was being asked.
Your question is/was about what to do with the currency accumulated in the game. Knowing that you know how to accumulate currency and even how you go about it is not relevant to what you do with it. In fact, that you know how to get it is implied by the simple fact that you are asking what to do with it. If you did not know how to get money, knowing what to do with it would be of little help to you.
Mentions of how you know to spend your money are not out of place, but as they were, you went at length to no end or clear connection to your question. You might consider revising that content back in at the start of your question to briefly mention that bribes and housing are things which you can and have easily afforded. This could mitigate answers that might mention these things, without going on at length.
Discussing your theory of currency's purpose in online versus offline RPGs does not really inform your question in any way. I don't see how this point makes a point as simple as "I'm at the end of the game with loads of cash and no idea what it's for anymore" any clearer.
You already asked if there was anything really expensive. Asking twice is redundant and that's probably why the second asking was removed.
