Especially if the media is readily available elsewhere which is always the case for movies you “bought” digitally.
Except when they aren’t. Especially if located outside the US, it is far from obvious that a given movie is available through another service.
Refunding the sale price is still theft.
What did you lose in this theft?
Is there really nothing in your home right now you would be sad if someone took and just gave you the money you paid for it?
Even a digital copy of a movie may not be so easy to replace on the services I have access to.
Stores are not allowed to go home to people and take back the stuff they sold, even if they refund the price. Neither should a company that advertise “pay this price and own this movie” rather than “pay this price and rent it for an indeterminate time”.
Here is a DallE rendering of the same setup that maybe is less offensive.
While a broad concept, in the context of your question, science is a metod to derive knowledge from observations.
Alternatives to the scientific method is to guess or to obtain knowledge from others. (Most other ways I can come up with, e.g. “religion” can still be sorted under these two.)
Obtaining knowledge from others is great, but may not always be available, and the quality of the knowledge derived this way depends on the reliability of the source.
For the other alternative, every sensible metric shows how science is a better method than guessing to derive knowledge.
But, “speedy” relative to what? Relative to the walls of the room your are inside? What if you are in a falling elevator? Relative to the rotating surface of the earth? To the center of the solar system? “Relative to the portal” is the only answer to that question that makes sense.
How can it not be b? Every situation in the Portal games is already exactly like this, but with the portal fixed to a slab that moves with the rotation of the Earth, whereas in the drawing the portal moves as the sum of earth rotation + the movement of the train.
Treating the question seriously, I think it is easy to think the one person is the right choice, because it just seems like less of a mess to deal with. However, I also think the end result is that you will never feel safe in your home again. You will always second guess if every squeak you hear is yet another person who somehow have made it into your house. This is the path towards slowly descending into madness.
After checking that you can open port 53 udp yourself with, say, nc (which you tried), strace the binary that tries to open port 53 and fails, and find the system call that fails. You can compare it with an strace on nc to see how it differs.
If this doesn’t clue you in (e.g., you see two attempts to listen to the same port…) Next step would be to find in the source code where it fails (look for the error message printout) and start adding diagnostic printouts before the failing system call and compile and run your edited version.
