Well, you could always bury some items that would be collectible a couple of hundred years from now. A coin collection would be a good candidate.
The difference between the banana analogy and freezing is that we actually can posit a hypothetical, reasonable mechanism for being able to revive someone. It’s an engineering problem, not a problem of basic science.
And you don’t have to cough up the money in a big lump sum. Just take out an extra insurance policy, and bequeath the proceeds to Alcor or whoever. Now your huge investment turns out to be maybe $30/mo. Hell, lots of people spend more than that on their stamp collections, so if this gives you peace of mind and a ‘hobby’ in following advances in the field and such, where’s the harm?
Hell, lots of people spend more than that drinking alcohol each month. Are you going to judge them too? How about the people who spend hundreds of dollars a month on a sports car when they could drive an old beater for a fraction of that?
Why must we always judge everyone else?
Now, if Alcor or other freezing companies were pure scams, that’s another matter, and I’d be fighting against them too. But from what I can tell, they are honest companies doing exactly what they advertise, and doing it with great care and respect. And they don’t misrepresent what they offer, either. They’ll tell you that we might never be able to revive these people, and they admit that future procedures will be much more likely to work than what they can achieve today. So it’s all on the up-and-up, all the cards are on the table, and people are free to make rational choices. I can’t understand how you could possibly object to that.
As for giving your money away to a foundation or something, isn’t that exactly what you’re doing? Even if you believe that the current freezing process is horribly flawed, the money you pay to be frozen is helping to fund research that may make it more likely to work in the future. That sounds like a pretty good cause to spend your money on, if you ask me.
But then, couldn’t we make the same argument to anyone who spends any money on frivolous things? Shouldn’t we put all our disposable cash into bank accounts so that we can leave it to worthy causes when we die? If you don’t think so, then you’re a hypocrite for objecting to people spending money to have themselves frozen.
