the coindesk article is a copy and paste article he spread to other news sources
he is part of DCG which owns paxos so the lack of mention of actual gold tokenisation companies is done to avoid it appearing as a promotion..
but
lets take Paxos as an example
they have a gold vault in london where each ounce has a serial number. which is minted into tokens and traded
where you can then trade in 0.01 token amounts (0.01 ounces)
there is obviously no storage fee becasue they know they stay in custody of the gold so at the end of the day there is no big admin cost. its just close the door and let it sit there.
they cover other admin costs like auditors via trade fee's and the obvious spot price spread deals they do
so the maintenance/storage fee is hidden in market trade fees
(much like how CEX dont charge to custodianise and audit bitcoin but CEX get paid by the market order fee's)

Pax Gold (PAXG) is a digital asset where 1 token is backed by 1 fine troy ounce of gold, stored in LBMA vaults in London.
this means 1 ''coin' is 1 ounce
PAXG can be purchased with or redeemed 1-to-1 for loco London gold.
PAXG offers investors a cost-effective way to own investment grade physical gold through a digital form of the underlying asset.
Ownership of PAXG is the equivalent to ownership of allocated gold bars. Purchasing PAXG is free from settlement and credit risk.
you can only redeem whole ounces
Pricing
PAXG pricing reflects that of the underlying XAU spot price against USD in real time. Trades minimum size of 0.01 TOZ.
you can trade using tokens at 0.01 coins(tokens) but remember only able to redeem whole physical ounces if you want them delivered to your home
Creation
PAXG can be purchased with USD or unallocated gold. Both forms of payment are converted into allocated gold
bars through an LBMA clearer and tokens are minted in relation to those specific bars. At any time PAXG holders can see the serial number, value and physical characteristics of their vaulted gold.
each serial number in token matches serial number on ounce of physical gold
Redemption
Institutional investors can redeem PAXG for LBMA accredited Good Delivery gold bars, unallocated loco
London gold, or for USD.
you can ask for the official token to be 'burned' and get official physical gold delivered(LBMA) or trade your token on secondary market with someone wanting to buy it with their unallocated(not in vault) gold (p2p)
Custody
Custody of the allocated gold backing PAXG is in LBMA
vaults. A nationally ranking auditor attests to the
matching supply of PAXG tokens and underlying gold
assets every month.
Custody of PAXG tokens is with Paxos Trust Company,
LLC, a New York limited purpose trust company regulated
by The New York State Department of Financial Services
silly thing about this
although LONDON has the LSE and fca and everything seems like its british. the paxos company are HQ in america with american licences and exchanges... not british
i will say this that LBMA has vaults in many countries. but having US regulations on a london vault/safe. is a mismatch of communication and jurisdiction
