Please do not put words in my mouth. I never said the DAS users were abusing the system by doing this. I think Disney has a broken system and this would be one step towards fixing it.
Disney 100% allows and even encourages it. However, as a non-DAS user I am a little frustrated with the idea that a DAS user can get on more attractions that I can throughout the day (thus encouraging abuse, making standby lines longer, and reducing LL inventory). In my opinion people waiting for a DAS rides should be allowed to experience any aspect of the park that does not have a line (parades, shops, restaurants, any attraction that has no wait time), otherwise DAS will negativity affect non-DAS users.
Daily ride capacity is basically a fixed number. Every time someone gains an advantage, an equal disadvantage is felt by those that lost out on that advantage.
