Yes, I have. There are already stacks of cardboard boxes filled with books. For everything that comes into the house, something must leave. Better if several things leave, so that I can once again have empty space and uncluttered surfaces.
I scanned all my old photographs and threw out the originals. I’m doing the same with my audio and video cassettes, after which I can get rid of the cassette deck and VCR. I might get rid of the television, as my computer can do everything I need a TV for. (I haven’t watched broadcast television in years.)
Move to a bigger house? If I could afford to, I would. But that would just put off the problem for a while, and lack of storage space isn’t even the main problem. The real problem is that stuff takes not just physical space, but mental space. Those old photographs are now organised by date and location in a folder on my hard disc, where I don’t have to see them. I know exactly where they are if I need to find one, but they aren’t a drain on my mental energy the way the boxes full of 3,000 pictures were. I have umpteen mid-ranking SF novels that I dump as fast as I read them, because a few notes in a bibliography file to remind me what was in them is all I want to keep.
I have no ambition to live with fewer than 100 things, but I live and work best in a clean and uncluttered environment, and looking round my computer room right now, that is not what I have.
