If there is no MU in crafting right now, where are crafters getting this extra coin to pay the extra MU to stimulate the economy? So trying to lay the entire cost on them is never going to happen, you'd just turn more away.
Until hunters have L weapons that are good enough to pay a MU on, Until hunters use L armour that is good enough to pay MU on, Until L tools are good enough to rival the UL ones, there are not enough reasons to craft and therefore not enough reason to pay MU.
That's very true, with a few exceptions. But yeah, from my point of view, once I realized the true cost of crafted armors, and understood that the alternatives (looted armors) were abundant on the auction and much cheaper in comparison, I stopped crafting armors and don't plan to ever craft any more armors again. So I suspect the same is true with weapons and tools.
But to get back to what OP proposed, I see 2 possible effects as a result of 'fixing' the logout loophole in space to evade getting killed and looted by pirates:
1. Further dilution of the Calypso community due to more interesting markups for mining resources and hunting loot on other planets.
or
2. The opposite reaction: current crafters moving their crafting operations to Calypso to take advantage of more competitive ingredient markups.
I don't think that either of the 2 possible results above would be desirable for MA. Mindark needs the Planet Partners almost as much as the PP need MA.
I remember my EVE Online days when I spent hours researching how to travel through space safely. There are ways to do it, there are a combination of awesome, expensive space ships that have cloaking abilities during warp, as well as skill based solutions that, practiced long enough, would make one almost impossible to catch (if I remember correctly it was an advanced cloaking device that, while it didn't allow you to cloak during warp, it allowed you to cloak almost instantly after teleporting through a stargate but only for 1 cycle, allowing you to align for your next warp, if you can time it right)
Unfortunately the Entropia Universe platform does not lend itself well to skill based solutions, it's more of a turn based game platform.
But the point is, there has to be solutions for those that need to move lootables through space, so if MA was to 'fix' the logout option, I would expect MA to introduce a new class of transport ships at the same time that would be impossible for pirates to take down. Obviously, these transport ships would not be able to equip weapons and would probably be pretty slow or whatever, but it would be a viable solution.
