Fucking shit, now I understand the problem. You just don't know anything! Good heavens, that's why we never came into agreement, because you used our own made up fanfiction.net level imagination.
Let's fucking play along. Let's say that anyone who is proficient with swords can be summoned as Saber, fine. I hope this logic I'm going to teach you goes through your adamantium skull.
Let's say I am a fucking legendary hero. I can use swords like a fucking Jedi, killing people like pro. I also can shoot your face from 100 yards with my bow. BUT I'm most famous for having a pimp ride, a 10 foot stallion that shits thunder and eats babies. Do you think I can be summoned in the Grail War as a fucking Saber or Archer? FUCK NO, I would tell my Master to go suck a dick and die, why?
NOBLE PHANTASM, remember? The weapon that defines the heroic spirit, symbol of their identity? Fuck, why would I become something other than Rider, when my symbol of legend, my pimp horse, can't have Rider stats buff? What's the fucking use if there's someone else, a Rider, who also has a ride that can outrun me? Could I become a Saber, while my sword is just some ordinary sword I got from my fans which has no mystery factor to define its rank? Could I become Archer, when I don't have anything else besides "I CAN SHOOT ANYTHING FROM 100 YARDS GODDAMN I'M AWESOME"? If I play basketball with my friends every Sunday, does that make me qualified as a NBA player? I'm pretty good with my three pointers, you know. Just like Francis Drake is pretty good with her cutlass, I'd say.
Drake is a Rider because she's famous for her fleet and rides a ship.
Iskandar is a Rider because he's famous for his army and rides Bucephalus.
Gil can be an Archer because he can shoot his Noble Phantasms from his vault.
Emiya is an Archer despite always wielding Kanshou and Bakuya because he shoots Broken Phantasm and Shirou was a good archer in his school, and his swordmanship is shit compared to other people.
Heracles can be anything but Caster because he can use his Nine Lives NP with fucking anything. Bow, sword, spear, even your mom.
Arturia has a riding skill yet she can never become a Rider. Arthur depicted in a drawing killed Mordred with a spear, yet she can never become Lancer. She can only be summoned as a Saber.
I don't care anymore if you keep fanwanking Washington or whatever. I even pray that Nasu someday will grant your wish and have your dear president featured in one of his work so you can shut the fuck up and end my misery. Right now I just want you to get your facts straight instead of making shit up with your limited knowledge and faggotry. BEING PROFICIENT IN A CERTAIN WEAPON SUCH AS SWORDS OR SPEARS OR BOWS ALONE DOES NOT QUALIFY A HERO FOR BEING A KNIGHT CLASS SERVANT. EITHER YOU MAKE A LEGEND WITH YOUR WEAPON OR YOU MAKE A LEGEND WITH YOUR SKILLS ON WEAPONS.
edit: I wanted to explain more about Emiya since he's a special case, but I can't think of some way to explain it without spoonfeeding newfags.
