Good post. However I'm not certain they are "advantages", it's very subjective whether you consider these advantages or hinderences, anyway here are my thoughts as someone who chooses to game on console:
I don't want full control. And these requirements wouldn't me necessary if it wasn't for the plethora or CPU/GPU/RAM/OS configurations available. The benefit of the console (PS4Pro/Scorpio accepted) is that devs have one set configuration to use their expertise to optimise to. I trust they know their game and vision better than I do.
An interesting idea and yet in 30+ years nobody as managed to improve upon the original Nintendo gamepad design save adding more buttons. The popularity of the DS4, XB1 Constroller and Steam Controller on PC says everything I need to know when it comes to this choice. Sitting on my sofa, 10ft from my tellybox, nothing works better than my trusted DS4.
As someone interested in playing the original Rome Total War on my Windows 10 laptop I can attest to how tenuous this claim is. PC backward compatibility is prone to just as many, if not worse, problems with OS and driver upgrades. At least on console it either works or (more than likely) doesn't. I suppose we need to discuss DosBox, QEmu and VirtualBox? Even then Win3.1/95/98 era can become a bit of an headache!
In short, you have a selling point, you're right, but you're also stretching the truth a little here. My PS3 however hasn't gone anywhere and plays all my PS3/1 games just fine. I also still have my XBox, which is softmodded, so you can guess the level of backwards compatibility there
Well. This is more an hobbiest thing isn't it. I wouldn't call it an advantage. If anything it's one reason I could cite while I'd actively choose console. It's only an advantage if you really, really are interested in the modding scene. For everyone else it's safely ignored. Move along, nothing to see!
You have me here. But...it comes at a price. I like the USFF/NUC style, so let's take a £550 Alienware and compare it to a £350 PS4 Pro...Not fair? Top end Alienware could kick PS4Pro's butt? Probably, but how much does it cost? But I could build my own cheaper? So not only do I loose the advantages of a ready made system, but I now have to choose from larger chassis?
It's good having these options...if you want them and are interested in this sort of thing.
Or I could just buy a PS4/XB1 unbox it, plug in to the TV and get on with the serious business of playing games.
Highlighted my point exactly.
I don't want to be experimental - I want to play games.
Well this is true. It also means separating the wheat from the chaff. Gaming on PC reminds me of finding good games to play on iOS or Android. I assume you'd advocate mobile over Nintendo for portable gaming? Sure there's crap to to wade through on any platform. Just so happens to be less of it with a generally higher overall quality (subjective, my opinion, please ignore Black Tiger even exists) on console.
There's also the question of what platform the games you wan to play are released on. When Uncharted (please don't mention PS Now

) is available on PC, give me a call.
The best point you've made and one reason I do game a little on my laptop, if I'm being honest. You can't beat a good bit of Civilization. Revelations on PS3 comes close, but it's no Civ V and you're right, a mouse really is needed.
Ah the economics of gaming. How much do we take in to account the initial purchase cost of the PC? Or the maintenance/upgrade costs over a given period of time? What about the console gamer, like me, that generally buys secondhand and trades in for credit towards the next game? Do PSN and XBox stores have sales and bundle deals? Especially for network subscribers?
I don't think the calculations are as cut and dry, black and white, or necessarily as one side as some like to make out.
Ah, yes, exactly! Well Done! So you do get it! You understand!
