It still seems like it could be worthwhile in the 2-3 year timeline if you were diligent about setting up good systems. I.e. you could set up a separate savings account that you put your yearly (monthly/weekly?) donation into and then donate every 2-3 years.
For me, at least, I think this would do a lot to decrease the cognitive load and temptation to spend. I don’t do this currently but am thinking about it. If you can truly think of the money as already donated when in the separate account (maybe a wealth front cash account?) this would solve a lot of the problems. I do think I would end up donating significantly less when bunching if I didn’t keep the money separate.
Up-voted for interesting idea and for reminding me that Huemer is blogging.
I’d tread very carefully with something as physically and legally dangerous as this (or the black market non-profit), of course, and consult with lawyers before even considering it—maybe something related to this is the reason for the downvotes?
I agree it’s a potentially valuable cause, but I think any less dangerous options that would move America towards allowing paid organ donation should obviously be preferred—off the top of my head I’m not sure what that would be, though.
