Hoping to not offend proponents of systemd/firewalld...

Linux kernel is already containing chunks of code related to 
systemd/firewalld and friends. One can disable stuff during kernel 
build, but the result it still is not like the result of building kernel 
before the existence of systemd/firewalld. Also, it is likely that at 
some point systemd-free Linux distribution(s) may fade away.

That said, if one is strongly willing to stay away from systemd, and not 
to such extent into Linux as to needing an advise on that, I would 
recommend to take a look at non-Linux system, specifically BSD 
descendants (FreeBSD, NetBSD, etc). Their kernel is not as heavy 
(big,resource demanding) as Linux kernel, and you can do pretty much 
everything one needs (except maybe computer games, although these will 
fall mostly into MS Windows scope). I for one have FreeBSD on my laptop 
(with alternative boot into Debian, the last being systemd though...).

I hope, this helps.
