Dumping the data from the client will still be fully possible. Regardless of what you do, it'll be able to be circumvented. Most you'll achieve is deterring noobs that don't know how to debug/reverse things.

I believe that it is precisely from noobs that you need to defend yourself first. Noob will definitely start reselling your developments or even giving away to everyone for free. A person who can crack protected files, as a rule, knows the cost of work and will often use the obtained data only for himself. So file protection will not be superfluous in any case.
