[int_19h]

Your argument seems to be that those 100 Mb include the necessary libraries. The problem with this assertion is that much richer runtimes don't require that much. For example, a .NET Core console app published as self-contained is ~65 Mb, and it comes with more libraries than Deno.

Well what is the size of .NET that I assume you need installed?

[int_19h]

You don't - that's the size of a completely self-contained binary, with .NET effectively baked in. A "hello world" .NET app that uses external runtime would be measured in kilobytes.
