"Bowls of fruit"..hmm. That reminds me of "sacks of grain".

These decisions were taken over by the American courts and so was FRB legalized. However, an interesting development occurred in grain warehouse law, which has developed in precisely the opposite direction, despite the conditions of depositing fungible goods were exactly the same, and grain was a general deposit and not an earmarked bundle.
In the history of the U. S. grain market, grain elevators several times fell prey to this temptation [FRBanking with grain], spurred by a lack of clarity in bailment law. Grain elevators issued fake warehouse receipts in grain during the 1860s, lent them to speculators in the Chicago wheat market, and caused dislocations in wheat prices and bankruptcies in the wheat market. Only a tightening of bailment law, ensuring that any issue of fake warehouse receipts is treated as fraudulent and illegal, finally put an end to this clearly immoral practice. Fractional-reserve grain warehousing, that is, the issuing of warehouse receipts for non-existent goods, was clearly seen as a fraud
So if FRB'ing with grain is seen as clearly wrong and fraudulent, why is FRB'ing with gold right?
Pyramid schemes are fraudulent. Doing it while wearing a tie, in a building with lots of glass and nice furniture that says "bank" on the front of it, doesn't change what you are doing.
You are comparing apples and oranges. The issuance of multiple bailment receipts for the same item (be it grain or gold or whatever) is fraudulent.
[1] The problem identified in the article snippet you offer here arose from the "lack of clarity in bailment law" (as the article itself explicitly points out) - it did not arise from the (supposed) inherent fraudulence of fractional reserve banking.
When Acme (a grain or gold warehouse) accepts a deposit from Smith and then, by willful deceit or through some loophole or weakness of the law, issues a claim against that deposit to Jones, both Smith and Jones have net claims against Acme for the same thing. Acme owes the same something to both Smith and Jones. This is fraudulent. It is a "pyramid scheme."
But when Acme (a fractional reserve bank) accepts a deposit (in the form of grain or gold or whatever) from Smith and then, in accordance with Acme's rights under the contract it entered into with Smith, loans some of that deposit to Jones, Jones does not have a net claim against Acme.
[2] Jones owes something to Acme, and Acme owes the same something to Smith. This is not fraudulent. It is not a "pyramid scheme."
Under genuinely free market conditions, there would be some degree of inherent risk for (demand) depositors at fractional reserve banks. This is why such deposit accounts at such firms would yield interest as a means of paying depositors for the risks they bear. Things like government-mandated and back-stopped deposit insurance and myriad other interventions (such as legal tender laws, central banking, etc.) completely discombobulate the market mechanisms which would otherwise regulate the practice of fractional reserve banking. IOW: The problem under the current system is not that some part of it maintains fractional reserves. The problem is that it is not free.
[1] Actually, the concept of "fraud" is itself rather problematic. I prefer to consider things solely in terms of contracts, and of whether the terms of any given contract were met or not. The question of what "fraud" actually is and whether a contractual failure is "fraudulent" (as distinct from just being a "mere" contractual failure) is to my mind superfluous and is in any case a can of worms in its own right. Nevertheless, for the sake of concision, I accede to common usage.
[2] Jones will have a gross claim against Acme if he deposits his loan with Acme (as is usually the case) - but he is obligated to pay his loan back, so there is no net claim. If he makes additional deposits of his own, then for that part of his account for which he is not liable, he is in the same position as Smith
vis-à-vis some other borrower Davis, and so forth. Under a free banking regime, this will give rise to market-derived "natural" reserve ratios, just as it will give rise to market-derived "natural" interest rates.
