I certainly agree with you that attempts to get credits out of the economy haven't been very successful, but to be fair to them I'm not really sure what they could do to solve this beyond a full character wipe plus a total rebalance of the price of absolutely everything in the game, particularly things that are consumable like nanobots and ammo, as well as things you can lose by dying like cargo. I think at the moment, limiting credit inflation is the best they can do.
Honestly, the question is - what do you actually want to do with multiboxing? Trading isn't fun at the best of times, multiboxing wont make it more fun or even more rewarding really, the latter due to credit inflation which will just make everyone elses credits worth less. You sure can't fight on two ships at once, and even the ability to RP would be questionable since people would end up RPing with themselves to provide the necessary RP background for an SRP request. After all, if people are scummy enough to stage an RP event on a private server while pretending it happened on disco to justify certain outcomes, and I know for a fact that this has happened in the past, then giving them just one more avenue to abuse the system doesn't seem like a good idea, even if it is relatively easy to detect.
The real question is probably not whether its possible, but what would the point of multiboxing would actually be? I want to be able to multibox between my banks so I can arrange my guns in a nice order in my trade menu, as well as just a simple quality of life improvement for making sure I can set up my own ships with equipment from my own banks in good time without having to rely on someone else to help me. This would only be necessary in Conn.
I must say I can't see any good outcomes for allowing multiboxing on a wider scale:
1. inflation of player count just increases server load without resulting in meaningful interactions, like fights or RP between characters due to limitations of the player behind them.
2. player count might be low now but if we do reach the player cap, then what? Do we ban it again, or put in a limit of some kind?
3. imagine a different kind of multiboxing, with one person setting up multiple exploration cruisers and mining sci-data from 5 anomalies or more at once.
4. putting multiboxing behind a paywall doesn't really help the people it would probably be most useful to, and even if it was a sci-data item, the real issue with the economy is that you don't spend credits or sci-data on something that eventually expires, it just stays around forever, like a car that never breaks down.
The economic rammifications of allowing multiboxing outside a very limited set of circumstances are both unpredictable and uncontrollable. And once you go black, you can't go back allow it, its not really a reversible decision IE the damage will have been done to the economy already. Not that it's in great shape to begin with but yeah.
