I’d agree that people are naturally interested in understanding the world, but the barriers to rigorous science you mention are present in every field that requires practice and dedication to master. Which is every field.
Most people just aren’t interested in doing the work to master anything, and that’s okay. You can still enjoy playing with a drum, doodling, or tossing a ball around without it being a gateway to the deeper mysteries of those fields.
The biggest difference is that science and science related content is much more capable of being hilariously impactful and dangerous.
As such, it’s easy for a moderately proficient person to do an experiment in their backyard that would have been cutting edge 300 years ago, and safely do things that we’ve all been properly taught are absolutely not safe.

People like novelty and mastery. People doing science video often convey a lot of expertise in addition to showing something new that’s also pretty, loud or just “bright colors”.

I’m pretty sure there could be a long muse about the intersection of the notion that babies are natural scientists, and calling someone an iPad baby.
