The thought of climbing ladders for the next 20 years or so wouldn't thrill me; so if WFP were banned, I think I'd do something else.
I think a WFP 'spoils you', if you know what I mean; I still use my ladder now and again on a small handfull of accounts; no more than ten; and use it to access flat roofs on a similar number, but the thought of using them all the time wouldn't seem like fun.
