I built some native apps for macOS recently and a 10MB installer with a below 100MB footprint after running for months makes me wonder what would happen if all of my apps were truly native.
Apple's ecosystem is incredible, all the APIs they provide, all the neat little native functionality you can build into your apps, all virtually for free, and a user base that cares about the quality of their apps and is willing to pay for it.
There's no better platform for building a native app, in my opinion.
