Seals do not always come out easily. In the case of the differential Seals I had to Hammer a Screwdriver between the seal and the Bore to loosen the Seal. (You will never see me recommend this method to someone because you need to really be careful doing it. Also in this particular case I did it at the highest point I could and Differential Oil is not under pressure and is thick so there is very little chance it is going to leak.)
That often nicks up the Bore. You can dress down the high spots but there is low spots to deal with. Sealant takes care of that.
Also when I worked as a Mechanic I did everything possible to insure that what I worked on was not returned for any reason under warranty. For me sealants were insurance against the off chance of something leaking.
Also the outer surface of a lot of Seals is just plain Steel. You do not want to install a seal like that without some sort of Sealant.
When something comes back to the Shop under warranty the Shop pays the Mechanic to fix it for Free; they also lose the Profit the Mechanic could have made for the shop while he was doing the Free fix, and often they lose a Customer.
The Shop also loses the Cost of parts and materials used to do the Fix.
