When you own a car, house or a boat you are responsible to make sure it's properly maintained, insured, and that the taxes are all paid so you're allowed to use them. Think about it, you cannot use the property you fully paid for unless you pay for it every year, on time. Before bitcoin everything else we could own was conditional ownership, we own them if the government say so. Standing for Bitcoin means you put your feet on the ground to truly own what is yours without any condition whatsoever.
Most people do not yet appreciate the unconfiscatable property of Bitcoin because they aren't yet in a situation where authorities take away everything they own no questions asked. The price of bitcoin can drop 25 to 50% tomorrow and it might take 2 years to recover but nothing cost more than a 100% lost in purchasing power or outright freeze on your bank account. Your bank account is not yet frozen because you are still being a good little boy/girl and by not transacting with the wrong people(your bank deemed to be) with the wrong amount.
A bank account can be credited any amount of money the bank wants upon a bank loan contract you're restricted to pay forever, just like the bank can debit any amount of money they want if you refuse to pay back or if you didn't follow the rules the authorities set in place.
Bitcoin removes the limitations we used to have in the legacy system where some people have all the rights and credits you don't have because you're not as wealthy or untitled to some special rights as much as them. The fiat system is based of proof of credits and weapons while Bitcoin is based on proof of work and merits.
Owning bitcoin even when the price is down is a sign you understand true ownership rather than allowed(conditioned) ownership, it's standing for something more than yourself.
