This accomplishes several things. First it encourages people to have multiple mechs, Second if your piloting a very expensive mech it gives the rush as you may not get to use your favorite mech for a day or two if you get sloppy. Third it acts as a good compromise between the "No risk is no fun" and "Losing work is no fun" crowds. Finally it helps encourage people to use more than just assault mechs (Longer cooldown) while still keeping the danger and fear they are supposed to inspire... Oh yea more mechs = more money for the company since people want to make their mechs looks cool.
You could also allow people to pull mechs that aren't fully repaired out of the shop and use them with existing damage (something you see in CBT campaigns is sometimes a mech fielded partially damaged or low on ammo sometimes even with a missing arm)
EDIT: Something like 2-3 million C-Bill per hour (assuming costs based on CBT prices)
