Firefighting isn’t profitable. Police services aren’t profitable. Parks and playgrounds aren’t profitable.
People who want those things would pay for them whether they are profitable or not. Just like NASA.
Plowing the streets and sidewalks isn’t profitable. Public art isn’t profitable. Keeping the air and water clean aren’t profitable. Teaching children isn’t profitable. Maintaining our highways isn’t profitable.
Yet we spend our money on these things. Why?
Because people value those services. It's not rocket science (excuse the pun).
Would you volunteer to pay for fighting fires in a neighborhood on the other side of your town? Or how about to pay for a highway that connects two cities you’ve never been to? Or to educate someone else’s children?
No, but I would willingly pay for those things that direct benefit me. I would also assist in areas where people don't have the menas to provide such things.
People are selfish, obviously including you.
It's not selfish to expect people to pay for what they use and not for what they don't use. "Selfish" is expecting (and forcing) people to pay fo things they don't want. The least selfish option is the one based on voluntary and compassionate action. Compulsion is selfish.
We don’t want to pay for things that don’t obviously benefit us. But we still want to live in a world where we have things like clean water, educated children, and people to put out our burning homes. Paying for scientific research is the same thing. We have governnments that tax us so that they can provide exactly those services that nobody is willing to voluntarily pay for.
If no one is willing to pay for them then no third party should be able to force us to pay for them. That's ethically corrupt.
If you want to live without them, why not try moving to Sudan or tribal Pakistan? Try living without the modern society you’re accustomed to if you really don’t want to pay for it. Give it all up. When you have, maybe then you can come back and tell us about how everything should be paid for on a strictly voluntary basis.
Ah, the old "if you don't like it you can leave" argument. That's not an intellectually honest tactic when discussing the protection of liberty and individual freedoms.
I still maintain that if individuals believe strongly enough in what NASA does, then they will willingly pay money to them. I would. What I do not support is the state forcing people (using extortionate means) to pay for such things.
