Well, a tripod is NOT an option in my business as a real estate photographer!
High Dynamic Range (HDR) shooting for real estate is a staple. I usually shoot HDR with 5 images, then blend them to get the best balance between interior and exterior lighting, emulating what our brain synthesizes from what our eyes see. I can't imagine doing this without a sturdy (not necessarily heavy) tripod.
Also, I'm a Google Certified Trusted Independent Photographer shooting 360 panoramas to "See Inside" businesses. While there are single shot 360 cameras out there (and I have and use the Ricoh Theta V), most of my serious work is done with a DSLR (D7100) or mirrorless camera (Z7) mounting a Sigma 8mm fisheye lens.
For each 360 scene you shoot four (4) sets of HDR3 or HDR5 images rotating in four quadrants. The HDR images are then blended and synthesized into a single 360 degree photosphere. I can't imagine how you would do that without a sturdy (not necessarily heavy) tripod. I use a Manfrotto 190 series carbon fiber tripod with an Acratech Spherical Panoramic Head.
As an example, my best shoot ever was last November 30th, 2021 where I was privileged to be the second photographer on a 2-man team photographing White House Christmas Decorations for Google.

After clicking on this link click on the arrow in the center to walk down the hallway of the East Wing and look left and right to enter the rooms beautifully decorated for Christmas. The White House is a national treasure. Enjoy!
The bottom line is that a tripod is not necessary for everything, BUT, for some specialized work, as described above, it is an absolute necessity.
