As you can see in this post I played mostly with xerath soraka and leona to climb. Your argument, by what i could see, is that if a player don't build support items or build outside the meta that this player is without a doubt deserving to be bronze.
You claim to have checked my match history and i believe you, but let's highlight some of the games that you overlooked:

I don't see even a sight stone here, and that was in plat already[i think].

Where is the upgrade of the support item?

I don't see a solari in it.

Neither in this game i see a solari in it.

Same example.
I think that that if the argument you were using was correct i'm suppose to be bronze. I'm not saying that there is no way to impact a game based on your itemization, but having tons of others skills and not doing wrong rotations and fighting decisions impact enough to say that items are not a bottom line to how you define ones elo.
Of course you are going to see that people with high elo they itemize better but the logic is that the higher you get more things you learn, and not that those particular items are the reason they are high elo.
Do you know what difference makes to me to invest and build a redemption at low elo to save a bronze 5 adc? Almost 0.
I will save the adc/jungler so he will jump again and kill himself in the end and i will see the mid laner using ghost to escape a gank just to walk back and die anyway.
As another example, Bronze players making qss is as good as a mana potion to vlad most of the times. They will die anyway by no kiting properly and many other simple things they just didn't learn yet. How is saying to them: "build that and you are suppose to get out of bronze" by any chance be correct?
Itemization sure have a space to help you winning matches but in low elo it's not what will rule all situations if you are literally giving up your advantages by so many other mistakes over and over. Also building support items every game is not the same as playing well.
To prove that to you here is a match of Ashe vs Ashe of me vs another guy how is a silver player with skills around bronze 1/ silver 5:
The challenge was simple: 1v1 i would only be able to finish a boot and BoTRK. After that i would only buy potions and the game would end at the 25 minutes mark.
The guy who would be against could build anything he wanted and have as many items as he want. In the other hand i had to play the entire match with only BOTRK boots and potions.
It was in howling abyss and we suppose to stop playing at the 25 minute mark.
What do you expect to see in the stats of this game?
Probably on your logic an almost even match until we both get the same amount of gold and then a complete stomp from the enemy player after he buy the very first item beyond the gold limit i have. Of course, if im restricted to have only bortk as soon as he have more gold equivalent than that i'm suppose to lose right?
Well that was my entire build the entire game:

That was his build the entire game:

That's how he ended in the entire game:

That's the match breakdown [i was the blue one]:

Those are my kills over comparing to his over time:

As you can see, even having 1, 2 or 3 items ahead of me i was completely stomping him until the 22 minute mark just based on skill and knowledge i had about the game.
What good a kill do to a bronze/silver player? Give him gold.
What good gold do to a bronze/silver player? Give him items.
What good an item do to a bronze/silver player? Give him stats.
What good stats do to a bronze/silver player? Nothing without the right skill to use it.
As it's demonstrated by my images, skill can count more than an IE+Runaan+Deathdance in a mirror match.
Trying to say to people that they are in their elo because of items is plain wrong and misleading.
Hope you can see i'm not trying to say you are a misleading person, but the whole argument make no sense to me in first place.
