What about ownership over value creation? If you're in a creative industry - and I consider software a creative industry - giving away your creations for a wage is psychically harmful. If you're genuinely creating something of value, you want to own some fraction of its value - its revenue-generating value, its future cash flow.
The other thing is that options suck. Options have so many conditions, vesting schedules, cliffs, expiry dates, negative tax repercussions... options are not equity. Options don't feel like ownership. Options are lottery tickets that might pay out, maybe. If you agree to be a wage slave for long enough, to give away all the value you create, see the big sales land and the annual recurring revenue build up, you might, one day, own a small slice of that cash stream. Maybe.
