Not sure if it will ever get a lot easier. The technology makes is very difficult. In addition, the addresses in wallets are hard to remember, a diffrent address for each coin, mostly diffrent wallets for several coins as most wallets don't support all coins... Not sure if this is the kind of effort the "ordinary" people would like to put in to it.
If somehow it got made easier, there would have to be some kind of person or company involved to make some changes. This would probably mean more costs which will hurt the decentralized part... Not sure but these are my thought... just putting it out there...
