No.

I am saying Bitcoin's value depends on it's convertibility into the USD.

Should the US government decide to take issue with Bitcoin, and make moves to suspend any USD denominated financial account linked to trading Bitcoin, then you will see the true value of your worthless vapour coin, and you will also see where the financial power lies. Any money that is exchanged for way way more than it's inherent commodity value, such as copper coins with gold and/or silver dye on them, bank notes, digital fiat or crypto, instantly become worthless the very minute the authority behind the denomination loses it's power. Thus, no USD, then no Bitcoin.

Bitcoin is a commodity whose utility is fast transfer of wealth and evasion of capital controls and covertibility into USD underpins all value that Bitcoin has.
