As someone who had to develop a DOS application for a job within the last ten years, let me say emphatically, no, DOS is not even remotely suitable as a daily driver today.

If you want simple nowadays, boot a Linux kernel into busybox. It'll boot almost as fast as DOS but you'll have all the crazy modern amenities like 64 bit support and network drivers.

You don't even need a package manager. You could just unpack a GCC binary and compile all the junk you want yourself.
