Legend
Lots of people suggest spending gold on stronghold or training (or carousing).The problem isn't that there's too much gold. The problem is that there isn't enough things to spend said gold on. Used to be that you had to spend money on training, or building a stronghold, or something to that effect. In 3e and 4e, it became that you needed gold to walk the magic item treadmill. In 5e? You don't need money. At all. Unless you have a specific need for gold, that kind of treasure is meaningless.
Problem is, there's no optional module for people that simply aren't interested in going into detail about what you do between adventures.
Gold in itself doesn't make anyone happy. But the way you could loot gold in anticipation of being able to buy some cool magic item for your character was a high point of 3rd edition.
That's not the same thing as "all these items wreck the campaign".
You only need to make a set of item construction rules that are better than 3E in avoiding abusive combinations.
5E would be even better if there was such a system, since not having a gold magic economy system is the biggest subsystem missing; it's the single biggest incompatibility for gamers who want to use 5E for their d20-style campaigns (since 3E/PF has drowned in its own complexity)
