yeah what nat said a mod or command is kind of cheating, if you lose nothing whats the point of even trying, mho only.
Wait what?
I was just laughing at the annoying irony of losing your inventory.
If you are not able to afford armour, you will not have armour.
If you don't have armour, you will die.
If you die, you lose your inventory.
If you lose your inventory, then you can't afford to make armour.
If you can't afford to make armour, you don't have armour.
If you don't have armour, you will die.
If you die, you lose your inventory.
If you lose your inventory, you can't afford armour.
And so on.
By the time someone is able to dominate a maze enough to make a farm and have renewable charms if keeping, they have MPS maxed advanced plating/energy shields and are neigh on invincible.
By that time, they won't die, and therefore won't need charms if keeping.
So the whole exercise was for nought.
Look at a typical inventory someone may have whilst mining early game and they die.
Compare to the amount if stuff you probably currently have, and the small amount whilst mining is insignificant.
However, that insignificant amount is probably 1-2 hours of solid mining, all to try and break this cycle.
Then they die and it's all gone.
Basically, once you successfully break this cycle, very little can kill you, and as such resources stop being so annoying.

I personally like /gamerule keepInventory true
You only die early game anyways, and its only early game that resources are SO valuable, by the time you have a reasonable setup, you don't die ever again, bar a freak accident with high energy pellets or something and so it doesn't matter that you don't lose stuff on death.
