The main value of crypto currency is its immutability. Immutability, as it pertains to blockchains, is the idea that the public ledger can not be altered. This is an important trait for blockchains to have for several reasons:

1)The moment the rules of the protocol change for reasons outside of technical improvements, you open up pandora's box: Who's to determine what the criteria is for reversing transactions? Why does one situation fit but not another? Is there a difference between someone who had their coins stolen or sent to the wrong address? If not, how do they prove their LTC was stolen?
2)Without immutability, the blockchain itself is no longer a useful tool for verification because it's transactional history is subject to the community and/or developers. The reason for this is because those who break the rules will most likely break it again.
For example, in June 2016 after the DAO hack, the Ethereum community had a choice: 1) fork away the stolen coins 2) deal with the consequences of the fork remain immutable. The community split which ultimately created Ethereum Classic and Ethereum.
Fast forward a year and a half later and they are once again considering another fork to refund people their ETH. Not only that, EIP867 is a proposal to develop a standard to recover funds in the future. Therefore, they expect and are even preparing to optionally change a ledger which is supposed to be used to reliably record transactions.
3)It maintains fungibility. If a protocol were changed to suddenly "blacklist" LTC addresses because it is assumed those belonged to a thief, 1 LTC would no longer equal 1 LTC. 1 LTC would only equal 1 LTC as long as it's not associated with certain addresses.
4)It removes the "god-like" powers of developers. They are no longer able to determine the fate of the blockchain no matter what their intentions may be.

Currently, the only 2 coins i know that have immutability are Bitcoin & Monero, which coin do you know other than these two ?
