Most bus users I know don't mind how far away the stop is, within a certain time. They really care about waiting long times at the stop because the bus is infrequent or unreliable.

Humans walk at roughly 2.1-3.0mph. "European cities" are listed as having bus stops 984-1476 ft apart, which would imply you'd typically walk half that to reach the nearest one (492-738 ft), which for a fit 3.0mph person is 2-3 minutes, and for a frail old 2.1mph person is 3-4 minutes.

Of course, people can be further away than that (they live orthagonally to the bus route), but you get the point. If you doubled bus stop distances to 1476ft apart, it would not add many walking minutes for the users.

Bus users can compensate for extra walking time by leaving earlier, provided the bus is on time. Good bus services can estimate arrivals in realtime, and show it to users on websites, apps, etc. as well as at the bus stop.

Bus punctuality is affected by a number of factors (e.g. traffic congestion, temporary and dedicated bus lanes), including number of stops.

The faster a bus can complete its route, the higher the route frequency can be with the same number of buses+drivers, which means buses pick up passengers more often, which means fewer passengers per stop (because less time between pickups), which means faster boarding, which in turn allows for a higher reliable route frequency. Having payment schemes like tap on/tap off, and having multiple entry doors also improves boarding times.
