No, no it doesn't. The change in weight is negligible (and only matters for carrying the bike, not riding it). Frame is what costs the money, not the gears. And the selection of folding bikes that are single speed are tiny.
And telling people to walk up hills? Seriously? Whiskey Tango Foxtrot.
Sure. Have only one gear if you want. Save more weight? Only one wheel.
