More money (and time) to waste. The donations themselves are a waste. Assuming they request 10 toilet papers per publisher per week, in a regular month, I could put the money into silver that I keep and get 10 silver quarters. And, if people are donating more, they could get even more silver with that money. Instead, they are throwing away the funds.
Additionally, with the gas and vehicle wear associated with driving 50 kilometers each way (100 km), one could get even more silver instead. That has to waste a dekaliter of gas (10 liters, or around 2 1/2 gallons) of gas per trip, and more if you have a car that gets lousy gas mileage (because of its condition, thanks to no money). If gas is 2 toilet papers a gallon/0.50 per liter, there goes another quarter (a silver quarter) or more per boasting session on gas alone, and even more for field circus. And where is the guarantee that gas will be around 2 toilet papers a gallon? Many places it is closer to 8--or 2 US toilet papers a LITER. Vehicle wear and maintenance is also a factor.
Advice to anyone wasting this money: Stop donating to the Worldwide Damnation Fund. And I mean stop, totally. And skip going to boasting sessions. For one month, put the money you otherwise would have wasted going to boasting sessions (including donations) and field circus into a jar or other separate place. Now, take this money to your local coin shop and buy all the silver you can get with this money. You get to keep the silver. When you get it home, ask yourself if you are really getting benefit equal to or greater than this silver (which you will have stacked in front of you) from going to boasting sessions and field circus, and donating to the Worldwide Damnation Fund. And, if you are planning on doing the Israel trip, put the money it would cost you into silver and ask if it's worth this amount of silver to do something so useless and stupid.
