ok I tried to explain it in simple terms, guess I failed, but here is the bitcoin wiki that says :
While Fractional Reserve Banking with Bitcoin is possible and already implemented with CoinLenders ........

https://en.bitcoin.it/wiki/Fractional_Reserve_Banking_and_Bitcoinagain you can fractional reserve bank anything, if you do not understand this, then you do not understand fractional reserve banking, it is just an accounting scheme. It is done with fiat, it was done with gold when gold was the currency and there is no reason why it can not be done with bitcoin.
You are showing the most basic and most predictable of all human responses: denial
You are missing a very important aspect regarding fractional banking, it requires an entity that can bailout banks and stop a run.
When we were on a gold standard banks implemented fractional banking on a much more limited scale, around 2:1, and still runs that wiped banks out were common. In today's fiat world the banks are levered over 10:1. The only way this is possible is because the FED can stop any run in its tracks by providing on demand liquidity, so runs are impossible becuase there is an entity that can bail them out.
In order to provide "on demand liquidity" the FED essentially needs the ability to expand the money supply on demand, i.e. print money.
In Bitcoin, this ability does not exist and there is no bailout entity that can provide on demand liquidity. Yes, the bankers will try to implement fractional banking on top of bitcoin, but they will be burned without a FED who can print bitcoins.
tl;dr Wall street can and will fractionalize Bitcoin, but without a printing press those attempts will fail, causing people to not trust or give their bitcoins to bankers who fractionalize, which in turn will prevent bitcoin from being fractionalized in the manner you describe.
