Meeting together once in a while is very different than either hybrid or in-office. I once worked at a small all-remote startup spanning from the west coast of the US to Eastern Africa. Yes, we all met in person for a week several times per year. That didn’t mean 3+ days per week in office.

And yes that company is still around and doing fine several years later even now. My last information on their in-person meetings is itself years old now, but when they got too big to have everyone meet in person together, they still continued the same principle, just in appropriately sized subgroups.
