There are a lot of unresolved issues around the notion of direct democracy. Referenda prove this point — e.g., the Brexit referendum and the EU-Ukraine association pact referendum in the Netherlands. In both cases media and pressure groups hijacked the process of forming an objective informed opinion, and in the Dutch case most people didn't even fully grasp what they were voting for — they just voted against out of discontent.

I am sure that there are ways to improve citizen participation in the democratic system, but directly voting on issues is not going to give us the sensible behaviour you might hope for. Representational democracy exists in part to prevent minorities from abuse by any majority — with direct democracy you eliminate that protection.
