Which commodity is the most expensive?

Okay, here's my attempt at making that paragraph sound more like something I'd actually say, you know?

"So, what's the most expensive thing out there, right? For ages, I was convinced it was rhodium. Like, the ultimate fancy metal, the top dog! But, man, I've been reading up lately, and wow, things are changing. I mean, seriously, data! Who would've thought information could be so incredibly valuable? It's kind of blowing my mind, to be honest. Iridium is another one that's climbing the charts, I think I read somewhere that it's used in electronics? And of course, gold's still gold, it's not going anywhere. But the sheer worth of data now... it's just... breathtaking. Is it even possible that it's worth more than gold these days? I'm starting to wonder if it really is!"
