You are wrong about what the article shows. It does not state the organic molecule forming a homochiral solution without a catalyst.

I didn't say it forms without a catalyst. I said "paper specifically shows how an organic system - without the need of an outside catalyst - can form a homochiral solution. It can happen without outside interference."
As Crofty pointed out above it's called an autocatalyst. Systems will always move to their lowest stable energy state. Thus one reaction can be a catalyst for another reaction.
All unguided attempts will always form a racemic mixture in the lab. That is a fact. It's science. It's chemistry.
Life didn't start in a lab or in a clean room did it? It started in the chemically messy outdoors. And just because you don't presently know how a homochiral system first formed in nature doesn't mean we just get to jump to the conclusion that it was an intelligently guided process.
We can't solve one mystery with another mystery. We can't explain one unknown by postulating the existence of another unknown.
