Grant, you have a great collection and I can tell by how you acquire art that you have curated a collection that very much suites your taste for art. Ver well done!
For me, the answer to the question is an emphatic "yes" - I learned that this is a decision I had to make early on as there are always pieces that are out of reach for me in terms of availability and cost. At some point in your collecting journey (different for all of us), you start to curate your collection and think in terms of what you want it to look like in the future. I don't want to stop collecting today, but if I did I would be very happy with where I ended my journey.
I have always told myself that I would like to start turning various non art collectibles into funds to by art but never have gotten around to it. I think I am nearing that time as I see some additional time availability in my future.
