Could you explain why, please?

After `udevd` on boot loads lots of unused crap, i surrendered, and use
$(rmmod `lsmod | just first column`). Networing bravely wipes away. OK,
there are lots of configs: udev, hotplug, modprobe, that somebody might
like to fix. But it came to the end with me. I just don't care. So,
please answer :)
