Unlimited items

I just told people about a command in essentials /unlimited
its
/unlimited itemname playername
it gives the player an unlimited stock of that item
disable it by simply typing the command again.

Now here's why i made this post... is there any reason we shouldn't be handing these out? I can't think of any, but i'm sure i overlooked something.

for certain blocks, obviously not a good idea, but for basic building materials it's probably fine.

Thanks for your input. Of course, i trust ops will be responsible with it and not hand out lava, fire and tnt
