I just think it's hard to imagine the type of edge that a universe could have, so it seems easier to accept that it has none. Maybe it's counter-intuitive, but it's pretty straightforward to imagine being able to go in any given direction for an indeterminate amount of time until all the galaxies recede into the distance and you're simply left with empty space. Like if you walk from the center of town outward long enough, signs of people start to become less frequent until you're off in the woods somewhere alone.
