If I rip all my CD's to flac files do I still need a CD transport?

I ripped my entire CD collection (4000+) to uncompressed FLAC using dBpoweramp. Took me 3 years to do it. I still have my CDs and I have upgraded my transport to a Jay's Audio CD3 MK3. Why?

1. I wanted to be able to make play lists and have my recorded music available for streaming over my home network.
2. I still like to listen to the physical CD and read the booklet. I like the ritual of pawing through my CD collection and finding something that I hadn't heard in a while. I also have a pretty extensive LP collection that I feel the same way about.
3. I'm bumping 70 and some day I may live in a situation where I can't have thousands of CDs and records. A bunch of these titles are not available on Qobuz.
4. I collect audiophile versions of my favorite CDs and I have multiple versions of quite a few titles. I like playing these physical CDs. It makes me happy.

If you don't value the task of searching for and playing a physical CD I'm not sure why you would keep a CD player. I readily admit I'm a dinosaur and my kids are going to have to dispose of a lot of probably worthless CDs when I go to the great listening room in the sky.

I have also ripped over one thousand CDs. I have not gotten rid of any of the CDs, I just never play them anymore. They line my walls and help with acoustic dispersion. Also still serve as backups in case ever needed (footnote: be sure to always keep a backup copy of ripped CDs somewhere...ripping is time consuming and once is enough).

As time goes on, there will likely be fewer CDs that I feel I have to still own as opposed to just streaming on qobuz or similar.

I also still have a growing record collection.  I ultrasound clean those and play once to convert to digital and add to my flac format music library.    

if/when in a few years time comes to downsize my home,  I will have to make decisions about what to do with all the stuff I've acculumated over the years.   Lucky to have that problem!

If asked my answer would be “Yes- you should always have a transport/player as a fallback”. I don’t know how many discs I own but a large majority of them (what I listen to most often) are ripped as .WAV files onto a playback server. When I buy a new CD it gets ripped and then stored away (99% of the time). The other 1% of the time is when I use a transport to listen to the music prior to deciding which discs to rip. An example being when you purchase a large box set. Two weeks ago I purchased two sets which combined contained close to 90 discs. This is a case where I want to listen to each disc first prior to deciding which to rip.

I stream a lot of music as well- helps me decide what to purchase on disc beforehand. But if internet service goes down a streamer is worthless. The server will still work via Wi-Fi but if it has an issue I can always play the disc. CD’s are cheap and compared to what you make selling them their not really worth getting rid of (unless space/clutter is the issue). 
Keep your player and your discs!

What happens when your hard drive chashes?  If you have the Cds, you can still recover the music. Do you have a storage space problem. I put my CDs on hard drives, but I still keep the media - just in case.

What happens when your hard drive chashes?

That's what backups and restores are for.   ITs' important to not overlook that because eventually every hard drive will fail.  Keeping the CDs is another safeguard but ripping thousands a second time is not a desired use of time.  So unless you want to be forced to go back to a CD player at some point,   have that backup and restore solution in place.  OR at that point punt and go mostly with streaming from services like qobuz, etc.
