In a way you are right. No one but God can prevent anyone from taking Communion unworthily. The Church cares for souls.

Mark 8:36

“For what does it profit a man to gain the whole world, and forfeit his soul?

I know this is a little out of context but for what do you risk your soul? Receiving communion is a priceless gift from Christ, He gives Himself body and blood, soul and divinity. But we are greedy and we want it all. We want to live our lives the way we want and then take the gift without repercussion.

If you are remarried without receiving a nullity of your previous marriage through the Church you are openly living in sin. Therefore you should not want to go against Church teaching at the risk of your soul.

[Bubba Ho-Tep]

I tend to avoid theological arguments, but isn’t it a basic tenet of Christianity that we’re all living in sin, openly or not? If the church barred every sinner from communion, the line would be very short indeed.

[PapaNew]

It's important to realize that by grace are you saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast (Eph 2:8-9).
