I have nothing against apps myself. Part of my road from a hoarder to my current situation was approving that iPad apps and plugins on my computer can replace a lot of the gear that I used to have as hardware. I’ve never been a “gold ear” who would distinguish a modelled Juno-106 from the real thing. I can just as well use a plugin. In the context of a finished song no one will notice the difference.
For me the core purpose of vintage gear has always been more about fetish for the “old gear smell” and the social stature it brings in certain people when you own a TB-303 etc. I’ve gotten rid of that thinking. I couldn’t care less for social stature or fetishising for old gear. When I had opened my Polysix for the 13th time to fix the keyboard bushings I realized that I’d rather have something to make music with than a hobby of fixing old synths. I love the design of certain vintage gear but for me it’s sufficient to look at a nice coffee table book of old gear.
I used to collect vintage video games too. Before it became fashionable. Back when you could buy a Vectrex for 20€ at a flea market. Nowadays I’m just happy to play those games without any hassle on my Switch or an emulator. I don’t have to own any of the actual machines even though they’re beautiful.
Even though my current setup is very limited and streamlined I often think of selling a bunch of gear still and getting something like an OB-6, Prophet-6, REV2 or a Waldorf Iridium in their place. That’s something I’d recommend to the OP too. Sell five or ten synths and buy a “super-synth” in their place. Learn to use that one synth thoroughly. It’ll make you very happy.
