I am a firm believer that hobbies were never meant to save us money, they were meant to save our sanity.
Of course, this is within reason given our priorities and constraints. Some really enjoy having the best and shiniest, while others really enjoy the building and figuring things out. There isn't one right way for everything.
I think the biggest question is if you are enjoying the hobby, and are spending within your means. If the answer to those is 'yes', then I think you are set.
I've been brewing for over 15 years now, and have accumulated over those years, so I know I have spent a very significant amount of money on the hobby ( A few of big ticket items are the walk-in cooler itself, the serving setup with 14 perlick 650ss faucets, the electric brewery, and the 90 kegs that I have).
I will continue to brew as long as I enjoy it, able to physically do it, and can afford to brew. Brewing is only one of my many hobbies, I have others as well that I divvy up the money for (I roast my own coffee on a behmor 1600+ for espresso with an ECM S-automatik 64 grinder and Rancilio Silvia machine, I am into PCP air rifles, also into charcuterie and have 2 year old procsiuttos hanging, woodworking and just bought a Laguna 12/16 lathe with accessories in addition to my laguna 18 BX bandsaw, plus other tools, etc.)
