The wasted time due to insufficient resource can be reduced to minimal if you planned ahead well and are in a high enough league to make 360-400K a day.
Things that are relatively cheap but take longer to upgrade like Airbombs LV3, 4, Guard Post LV4, Crushre Lv4, for example are the key to your planning. These take 1–2 days to complete but only cost around 300K+. That combined with some elixir upgrade you need to do should give you enough time to collect resource needed to upgrade the next thing and keep your only builder busy most of the time.
Also keep in mind that even when your builder is idle (when you don't have enough resource for the next project yet), having the upgrades done faster mean you can spend more time battle for trophies with full capacity with less chance of losing due to an important defense (or your Battle Machine) being upgraded.
All that said, I understand your point, and with the coming up BH6, the upgrade time will likely go up to 3-4 days. That could be a real problem, but as it stands right now, I still think the current CT helps a lot.
