You are creating more problems and solving none.

I disagree.
Then again, I am an electronics engineer by trade with degree in electrical engineering, so it seems overly simple to me.
There is a keen advantage to having everything on its own fuse. For one, if your headlight wiring shorts, you still have everything else functional. If not for the headlights being on their own fuse, you'd be dead in the water doing it your way.
Currently, my car is wired with the one fuse on the starter mounted fuse block, and when the horn got stupid, the whole car was dead. That made me cuss (and I don't cuss as a rule). Once the horn is fed off of its own fuse, the next time (if ever) the horn wants to get a mind of its own, the car is still fully functional, lights work, etc.
Also, having seperate fuses for items like interior lights, etc. makes troubleshooting easy. If your interior wiring was shorting out, you can pull the interior lights fuse and drive the car to the parts store to get the parts to fix it!
And, it's just plain a lot safer. For example, let's use the above interior lighting wiring scenario. Let's say the wire running to the interior light in the headliner was rubbing on the body metal and wore through and was making intermittent contact. There's enough small diameter wire between the short and the 30 amp fuse on your starter mounted fuse block to allow enough current to pass to create heat, but not enough to blow the 30 amp fuse open. What does that mean? That means enough current will flow through the small wire in the headliner to create enough heat to catch the headliner or cotton batting on fire and cause your car to burn to the ground. When having the interior lights on its own smaller 5 amp fuse, any shorts in the small wire would blow that small value fuse open, disconnecting the circuit, and saving your car (and garage) from catastrophic ends.
For those who do not have the ability or expertise to rewire your car correctly, the starter mounted fuse block is sure better than nothing! But, for thos of us who do have the expertise, it is a LOT safer way to go. Besdies, after re-wiring the car with brand new (period correct looking cotton covered) wire, it will be good for another 80 years or more, right?
