I don't really see the point if you then have to take it to a shop to get it inflated anyway...
The one time I tried this (tyre changing, not zipties) at home with a tubeless tyre, getting it to hold air without access to a proper compressor that can shove in a
lot of air was the big pain in the arse. (As in, I didn't manage and had to take it to a shop anyway.)
That little exercise just proved two things: One, I can put a tyre on, checkbox ticked. Two, this is completely unfeasible to do "in the field" and if a tubeless tyre comes off the bead, you're pretty much fucked.
It's a neat trick though. Tying the beads together so they easily fall into the center slot. I'll bet a few zipties won't actually make the diameter of those steel cables any larger.
