First, tubular tires are ridden today.
Second, they are safer after a flat than a clincher, because they stay on the rim.
Third, part of learning to deal with them is to deal with flats. As has been said, you slit open the seam, patch the tube, sew it up. Treating them as disposable is as silly as saying "wow, my derailleur needs tuning, I'd better just get a new one."
Unless you have a lot more money than I do.
