Yes, that's right, everything is tied to fiat.
Even if a baker sells his bread for $5, it is still beneficial for all of us that the baker is educated and understands that using fiat currency = total control (especially by banks and other non-cash forms of payment) = being robbed by the state and bankers through inflation.
Also, I don't want the state to rob the baker on taxes, and it is in my interest (out of human kindness) to teach the baker how to use Monero so that he can teach his family and friends, so that more people can circumvent the state's prohibitions, regulations and taxes.
The more educated people around me who know how to properly bypass the state and not get caught, the easier it will be for all of us to live.
And the more people see the value in XMR (for example, thanks to its default privacy and cheap ~0.02 USD transactions), the more the price of XMR will naturally rise.
That's why I don't care about the price of XMR.
