I do drive everyday on sunlight; it's called installing solar panels on your roof. Superchargers in cities are a very last resort because it's part of the old stupid "gas station" model. The beauty of an electric car is that it is fully charged every morning without having to ever charge it up unless you are driving outside its range.

I don't think you have a good conception of the range of the Model S. It would be extremely difficult in city driving to exceed its range over the course of a day even if you took several trips from the suburbs into the city and back.
I think gregincal has it right. Tasdevil, I'm not sure if you fully see the benefit of having an EV. If there is a plug, you can charge it - especially in Australia. We have the advantage of our regular electricity being 240V, which means that charging for daily city use can generally be covered with using a regular power socket on a standard 16A household power circuit. If I owned an EV (unfortunately I don't at the moment) I would probably get a dedicated higher amperage circuit installed at my home for faster charging during off-peak hours. However, that doesn't mean using a "regular" outlet doesn't work.
Let me give you a hypothetical scenario. I recently visited my parents in Queensland for Christmas. If, in a couple of years time, I own a Tesla and there were superchargers placed along the Pacific Highway, I will be able to make that trip (from Sydney to Brisbane) without modifying the way my family travel to Queensland. We stop every couple of hours for at least 20 minutes (a basic requirement with kids) for a bathroom break and to stretch the legs using our current car, so using the superchargers would not add any time to our 900-1000km drive. When we get to my parents' we will be able to just plug into one of their regular power points in the garage each night using the Tesla mobile connector (which comes with the car). No need for superchargers in Brisbane. I would be surprised if any place you stay at would not have a regular power point for you to plug into.
Assuming you are charging at 240V and 12A, you will be able to top up each night with more than 150km of additional range using a regular power point. I'm assuming charging from, say, 8pm-8am. Have a look at the charging calculator on this page:

To figure out how long charging would take on a regular Aussie powerpoint, change the outlet on the calculator to NEMA 14-30 and then double the time figure in the top left-hand corner of the calculator (which is kinda like changing 240V at 24A down to 240V at 12A). It won't be totally precise to the minute due to the different amperage, but it gives you an idea. Having over 150km top up each day is more than enough for while we are there, even if we were going to the beach or a theme park every day. On the other hand, it would be way less convenient to have to go out of my way during our stay to get to a supercharger a few times (and wait for 20-30 minutes on each occasion) compared to just plugging in each night (Elon made this point rather emphatically in the shareholder meeting video you referred to, Tasdevil). My parents also have solar panels on their roof, so I would also be using some sunlight for my charging.
As for expecting to not have to pay for ANY electricity for your car, I can't help you with that feeling of entitlement.
