Agreed, I was specifically talking about the desire for them to compose. I am familiar with legos absolute requirement on tolerances... which achieves what you mention. But if I am going to buy all three of my daughters lego (which I have) knowing that they will not hold on to them for "decades" -- I'd rather they have a blast when they are a kid, and then move on to whatever, and the blocks can go into the ground without worry. Yes, I am familiar with block exchanges etc... I have no desire to manage the post-market-post-play relationship I have with LEGO. LEGO should be literally all over that service. "Send us your unused lego and we will provide them to a nice farm Up-Site" sorta thing...
