To add all of the runes, daggers and other things that the rest of has have spent time and effort collecting would completely devalue what the rest of us ironmen have done.
It's a part of the challenge - to see how you can progress with limited help.
Runecrafting isn't bad (once the cosmic altar gets fixed) complete your achievement diary's for rune pouches and you'll be good to go.
Slayer is also a great way of obtaining items that you'll need anyway for gear upgrades and a fair amount of runes.
If you're ever in real need of runes, spending an hour or so making the runes required is essentially what you do at the beginning of ironman mode anyway - you often don't have enough cash to buy everything you need thus the prices (if they were added) should be extortionate.
