It's true that the opinions and comments don't matter. At the end of the day, they're just meaningless internet points and text that will be lost when the disk of my instance eventually gets formatted or when bit rot gradually eats them away.
However, that's not how my social monkey brain feels about it. Some primitive part of me that ignores all logic and reason clings to the notion of social acceptance and shivers at the mere thought of rejection. Can't disable that sort of thinking. Seems to be a hard-coded part of a function or something.

That's too much for walking. I would take a bike in that case.
Here's what I consider common:
In total, that's going to be like an hour, but it's divided into multiple parts. Walking that much in just one direction is something I would prefer to avoid. If the library is a 60 min walk away, that's the same as like 12 bus stops or 15 minutes while sitting in a bus. BTW that 15 minutes includes walking at both ends of the journey. I would definitely choose public transport over walking in that case.
If the destination is just 15 minutes walk away from your house, that's perfectly normal, and not a problem in any way. If it's like 20 minutes away, I would begin to consider using a bike or maybe even a bus.
