First of all, holding bitcoins does not qualify as pyramid scheme as there is no pyramid nor anyone at pyramid top earning more than other investors. The percentage of earning by all investors is equal. For example, if Bitcoin moves up by 10%, the fund of every investor, whether small or big investor, moves up by 10%. The earning is linear or flat rather pyramidic.

Ofcourse, we need Bitcoin to be used more as medium of exchange but it's still OK if people decide to hold or use it as store of value. That is basically part of its purpose.
I think it's best to create a decentralized economy that's parallel to the existing centralized economy and is based mainly on local exchange of physical products produced by the economy participants. This is much better way to start, so that governments don't feel too threatened by the activities participants since they are independent of their economies.
The decentralized economy can also be self-sustaining and mutually beneficial... meaning everyone patronizes each other, or a buyer/consumer buys what he needs from seller/producer and the producer reciprocates (though not compulsory) by buying things he need from the participant who previously bought things he sells.
The bitcoins also circulate within the economy rather than selling them mostly for fiats, thus helping it  to be self-sustaining and independent of centralized one
