Jay Jardine and Polspy have come up with the idea of making ourselves "costly to govern". One commenter suggests mailing rocks to PMPM if the postage really is free.
Send rocks to:
House of Commons
Probably the best way is to do your part to ensure that the Liberals do not have another huge surplus to play around with; try to do as much purchasing from the "underground" or "informal" economy as you can. Taking production out of the "formal" economy means although there is still the same level of economic activity, not as much of it is in the formal sector where it is taxed.
Also, I would suggest forming your own local currency to put a dent in the inflation tax levied on all savings.
