Yeah, you wouldn't be able to create that particular layout with just core blocks alone. Of course, recreating everything from core is not the goal. It's possible for a theme to handle most of it with custom block styles and patterns, but you'd need a block plugin or two that handled some things like tabs, sliders, and animation.

All of it is definitely within the realm of what the block editor can do though.

Even a traditional theme wouldn't be able to handle all of those elements without a boatload of theme options either. And, generally, that would be far less flexible for the end-user if they wanted to make any changes, such as moving sections around or adding in new ones.
