The problem is with tap water most cities and townships add trace chemicals to the water to help keep it safe to drink and depending on where you live there can be anything from heavy metal traces to chlorine to copper and so on.
The tap water may be perfectly safe to use but at the same time with RO and RODI water we get to control the variables and with tap water you might be able to use for years on end but that one time could cost you dearly. Most of those who use RO and RODI water will probably agree that it is better to control the factors and not leave it to chance because realistically we have a lot invested in our tanks I would rather be safe than sorry.
