Remember, that 2+ MB is the download size of a bare-bones application. Relevant sizes for real-world applications, obviously, would be bigger (though, depending on the total size, the Blazor part might or might not be essential).
Download sizes are definitely a problem but they’re not really a Blazor-specific issue these days. Also I would be curious to learn about the relative density of JavaScript bloat vs Blazor download sizes because the .NET class library is much more feature rich before adding dependencies and I could imagine bundle sizes actually being smaller for similar functionality above a certain point. But you’re right that it’s probably never going to get as small as a pure HTML + CSS app with progressive enhancement and minimal JavaScript.
