I will give you another good reason... money !!
They cash in a lot of money in advance, put it in the bank and get paid 
interests on it.

Oyster
Let's say you top it up £20. It could then take you any "indefinite" 
length of time to spend that money (one week, one month, etc.).
In the meantime they have that money in their bank account and get paid 
interests on it. If you multiply that for the number of Oyster cards 
around, I am sure it makes millions of pounds.

Old tickets
You only buy the ticket for your journey the same day you are travelling.
