I have flown down to the burn for my last 3 burns. Two hockey bags on the plane and I bought some stuff when I got to Reno. I could probably do a burn with one hockey bag of gear and buy misc supplies (aka food & water) once I got to Reno, but I would miss stuff.
All things being equal, I prefer to drive down - thus allowing me to bring all the gear I desire. It is nice to have my own shade, lawn chairs, lounge chairs, big dust-proof tent, cooking gear, cleaning gear, shower, tables, etc. I just do not like driving 3000Km by myself to the burn. And that drive home seems like 3000 Miles. . .
I know exactly what i need to be minimally comfortable, also what I find makes my burn more comfortable (beyond bare bones camping). It is highly likely, that some gear I cannot do without many other burners cannot figure out why I bring it. I am fine with that. It was my third burn before I started to get my gear sorted correctly - figured out my needed and unneeded stuff. Every year since I have been adding and removing stuff as necessary. (Although each burn has different weather, a burn with no real wind is very different than one that has 70 MPH winds every day...)
One of the things that makes Burning Man a bit more challenging than other camping experiences is the remoteness. Being totally self reliant means you need to bring it if you wish to use it. Also the climate. Super hot during the day, close to freezing at night. It is fairly dry, and at a higher altitude than many are used to.
I come from Canada, so I tend to do ok in the cool. I, however, find the heat to sometimes be a challenge. The altitude does not seem to be an issue. (I still bring warm clothes - but I also normally wear shorts when its 30F (-2C)
I am stubbornly self-reliant. Suffering, rather than asking others for help. Therefore I make sure I have my bases covered. (including extra batteries and spare flashlights/headlamps).
In the end, no one can tell you that you are "doing it wrong", but if you are not adhering to the basic Burning Man principles - you are not really doing it right either.
