Why are dozens of 18650s the best solution for high watt projects/products? Like, I’m sure the Tesla battery isn’t just a thousand 18650s, so why do so many (diy projects and professional products alike) just scale up by adding more of these relatively tiny lipstick-tube sized cells?

For most projects – including most commercial projects – having the perfect component is less important than having a cheap, readily available component.
If you’re designing an iPhone – which is going to sell millions of units and has critical power/weight/form factor considerations – you’ll design a custom battery. But if you’re just making a flashlight? You don’t need the perfect battery and it’s not worth the investment it would take to design/produce the perfect battery so you just use ‘off the shelf’ parts.
