When Moses died God could have cremated him to ensure that nobody found his body, but the He said He buried him.
Baptism is a picture of death, burial, and resurrection.
Picture this scenario: government rules burial illegal (environmental concerns, overcrowing, etc), 3 generations later a young man gets saved, you explain (due to his question, or the message, or Sunday school, etc) baptism and he has no clue what burial is.
I personally have no desire in being party to marring a picture that God set forth.
just my plug nickle, btw - this is OLD fashioned preacher, not Germany4Christ
