Start small. It'll save you money, let you get your feet wet, and help you learn how to grow better, and then you can buy bigger.

My "starter package" is:

• A 2' x 2' x 3' grow tent - $55.

• A grow light ($90). I prefer COB's as they're easier to fix than blurples.

• A power strip zip-tied to a pole in the tent. Makes wiring prettier and easier. ($24) I chose a nice metal one, but you can use a cheaper one.

• Hangers to hold the light ($8)

• A fan and filter ($70), and variac ($90) to filter smell and move air to keep things cool. This combo is overkill for this tent, but I ended up using it on later tents so it's a good long-term investment. You can cobble something cheaper together with some work, but this "just works" out of the box.

• 5 gallon Smart Pot ($7) for growing, FoxFarm Ocean Forest Soil ($16.50), Plant saucer ($7) for growing. You can save some money here by shopping around. In particular, Amazon's price for FFOF is about double what I pay at the (very expensive) local "indoor gardening" center.

• Go Box Plant Nutrients. This should last you several grows.

• Seed of your choice (let's say $10).
  
  So for about $420 (heh), you can get your foot in the door and start growing. This is a nice setup too, you can probably save $100 by shopping around, buying used, or doing-it-yourself. I've left off a few odds and ends like dryer duct, Fiskers for trimming, weed fabric pins for low-stress training, pitcher for watering, Mason jars for storage, but you can likely find those or suitable replacements around the house without spending money.
  
  I also have a Raspberry Pi 3 ($43) with Sense Hat ($37) and metal case ($15) in each of my grow tents to log temperature/humidity and other things. I'm interested in eventually using the GPIO functionality to water my plants too. Not critical, but definitely a nice thing to have, especially if you're the hacker type. If you go this route, you might look at raspiviv.com too.

  I'm glad I bought a good intro setup because I still use it now that I've upgraded. I now have a 3' x 3' GG Shorty tent with HLG 300 LED for flower, a 2' x 2.5' GG Shorty tent with two 400W Roleadro COB's for veg, and my "intro package" is now my germination/cloning tent (and drying tent too since several people suggested that too). Being able to have three tents (germination -> veg -> flower) working simultaneously is increasing my output quite sharply. I'm doing this to help a relative with cancer, so you may not need to go quite as crazy as I did.
  
  You mentioned using 35+ gs (~1.25 oz) a month. You probably aren't going to be able to grow that much given the constraints of tent size and light wattage (plus being a first-time grower! You'll learn a lot!). So once you get used to it, you'll probably want to buy more stuff. Marijuana isn't addictive, but growing marijuana absolutely is.
  
  Once you've got your hardware, the variable cost is seed (~$10), soil (~$5), nutrients (~$20), and electricity (~$30). From that, I'm going to estimate you can grow ~1.5 ozs (you can do more as you learn more though). So you're looking at ~$40/oz after you've made the initial hardware investment.
  
  Hope this helps. Depression, cancer, and everything else can just go suck it.

They make 1ft power cords, called outlet savers, solely for this purpose. It's going to leave a mess of cables though.

Shop power strips have outlets extremely spaced out. Obviously at the cost of space and price.

Like you said a system in place would solve this mess, but it's difficult getting everyone to agree on changing their standard. Relevant xkcd.
