As a student pilot that isn't IFR trained yet, we always fly visually and don't use the ILS. How I land depends on if it's at a towered airport, non-towered airport, or if I'm coming in from 10 miles out or if I'm already in the vicinity of the airport.
TL;DR what you're missing is that most pilots start out as VFR only and the last thing you want is to be distracted by things inside the cockpit like GPS devices, tuning an OBS, loads of instructions from tower controllers, etc. Every pilot needs to able to fly the airplane without the assistance of an ILS or a GPS.
General Final Approach
On final approach, if flying visually, we power up if the aiming point is descending in the windscreen and we power down if it's climbing. Power is altitude, but may require a corresponding pitch adjustment.
If we get slow, we nose down and vice-versa if our speed is a little high. We adjust power as necessary based upon our pitch adjustment.
These are fairly straightforward. We enter the pattern for the runway we've chosen at a 45-degree angle to the downwind leg. We then turn base then final and end up 1-2 NM out on final, ideally 500-600 feet AGL and descending at 500 FPM. Again, this is a purely visual landing where we're focusing our aiming point in the window and trying to keep it steady by using power.
Towered Airport Landings
Most of the towered landings I've done the controller has said to advise when 2 miles out and told us to aim for a base leg for runway X. We then fly a decently long base leg, turn final ideally at 500-600 feet AGL, and land just like at non-towered airports.
The controller could instruct us to do a 10-mile straight in, enter on the downwind, enter on base, etc., but it just depends on traffic and controller load.
I have yet to be instructed to use the ILS as a visual (VFR) pilot and I wouldn't want to b/c as a student, it's very helpful to learn ground references, ground track, crosswind correction, etc. without the assistance and distraction of in-the-cockpit devices.
