I don't think trivializing travel is the agenda.. I think it's exposing a hole in the content around travel mechanics.
People say space is big... well it is.. BUT
Back in time, so was your town. People never used to travel far from villages until a better method of transport came to be, the horse and cart opened local trade etc.
Then people said the county was BIG. Horse and cart was sill a major issue, travel took lots of planning and it was only done when needed.
Then people said the country was BIG until cars made the country a lot smaller. Motorized transport facilitated leisure travel and as cars become more common, people travelling the country became easier, and quicker.
Then, people looked to the horizon. The Earth IS BIG! With the dawn of aircraft, it made travelling between countries easier and quicker. No longer were people stuck in their village, they were basking on beaches in another continent. Today aircraft are still getting bigger, faster, more reliable, and cheaper. Now, you can bask on a beach the other side of the world in a matter of a day.
Then with the dawn of space, people started to leave earth. People thought Earth was big, the solar system was HUGE! but, as propulsion systems advanced, man began to build colonies in space, in giant stations. Man made objects the size of entire towns. People could traverse the solar system in a matter of hours. People could get up out of bed at 7am, and from earth, go on a day trip to Neptune, take some holiday snaps, and be back on earth in time for a light lunch. The solar system wasn't so big after all.
THEN came hyperspace travel. Neighboring systems were seconds away. Now, you could visit Cirius and be back in an afternoon. Mankind had conquered interstellar travel, our sector wasn't so big after all.
THEN with the dawn of quantum slipstream drives, we found ourselves being able to traverse distances our ancestors would have thought only possible by the gods. Technology had arrived that got us to the other side of the galaxy in the time it took to have a bath... The galaxy wasn't so big after all.
Explorers turned their gaze outwards. Andromeda was in sight. The birth of the singularity drive had arrived. Test probes have proven singularity drive propulsion to be safe, and a monkey has made a round trip to the outer arms of Andromeda in 2 days. Scientists are confident that mankind will have its first outposts there in 18 months.
Lets stop hamstringing ED with silly limitations. Technology progressing means freedom beyond the limitation of arbitrary lore.
The Galaxy IS big, but, so once was our villages.
