You don't buy from a consolidated address holding 14 BTC. That's not how it works if you manage your UTXOs properly.

Those 14 BTC are split into UTXOs of 0.01 BTC. When you buy something for 0.000123 BTC, your wallet only uses one of the thousands of addresses your hardware wallet generates — an address that from the outside only shows 0.01 BTC.

That transaction creates two outputs: the 0.000123 BTC payment to the seller, and 0.009877 BTC in change that goes back to your wallet at a brand new address, with no visible link to the previous one.

Of course, if you hold 14 BTC you could also have larger UTXOs — that's up to each individual and how they choose to manage their privacy.

First you need to understand how Bitcoin transactions and the blockchain actually work. Then you can work with that knowledge instead of assuming everyone operates from a single address.
