Let's have another chat about the ban on cloaking. It comes up occasionally, & there's one point of view I rarely see represented, relating to why it's actually a good in universe policy for the UFP.
You'll never hear me argue that cloaks wouldn't be highly beneficial to Starfleet's ships. They SOOOO would be.
The issue you have to examine is why someone would want to deliberately abstain from using something that would be so highly beneficial. What could NOT using cloaks offer that would be better than those benefits it could provide?
The answer has to do with complex relationship dynamics. The United Federation of Planets' intention is to be a benevolent organization of unified galactic bodies. Unlike the Cardassians, Klingons or Romulans, which have empires of conquer & acquisition, it's made up of parties who join voluntarily, for the greater benefit of cooperation. As such, one of the most prominent aspects of being able to maintain a group of volunteers, & maintain that group's exterior relations, would be that it can universally be viewed as nonthreatening, and one of the most beneficial ways to assure your image of benevolence, is literally to be as transparent as possible.
In brief, If the UFP is or becomes a group, with a defining characteristic of being able to be hidden from the people with whom they interact, they become harder to trust, for enemies sure, but also for allies alike. In fact, showing up to the table with it, after a potential adversary has already had it, might even been seen as an aggressive action of an arms race kind, which could destabilize your support
So, it's not in the best interest of the UFP to have its integrity, & its foreign relations disintegrate, once everyone starts realizing that they skulk around in secret invisibility. For an organization that depends on unity, such a posture would be epically disastrous. The better avenue of tech advancement would instead be to find ways to nullify the advantage with better detection... & then share that knowledge. There is a moral high ground in being the non-aggressor this way
Starfleet: We are the guys you don't have to worry will sneak up on you concealed. We've got nothing to hide. That, my friends is how people trust you, & if you stop having that, it's how people stop trusting you, & ultimately the UFP is nothing more than a galactic trust. Without trust... you're just the Ferengi
