Its a fine sentiment, but hardly "the only argument ever needed".

I had a conversation with a good friend of mine that give me a better understanding on why this argument isn't strong, and doesn't work in practice.

My friend explained to my why he believes the Heisenberg Uncertainty principle -- and most of Quantum Mechanics is wrong, and the world is, consistent with classical mechanics, properly interpreted. His arguments included numerous examples and appeals to phenomenology and equations.

I can't recreate his arguments here, though I "sort of" followed them for most of the hour of discussion, but I can't hope to determine what value his arguments have -- if any, and in spite of my degree in Physics, I couldn't make a judgement on this "belief" without hundreds of hours of hours of study and in depth discussion with him. While I don't think of him as and expert in "exactly" this field, he does have a PhD from MIT, and many years of highly respected experience in closely connected fields.

This holds a nugget for why believers believe -- they don't have the ability to make an independent judgement about the world, and one respected group says one thing, while another respected group says something completely different. At some point, you need to make a judgement on the value of the source, rather than the "facts" that the source presents.

That's why we need to have a strong public school system that is free of political influence, whose only charge is to teach well-vetted facts.
