No need to expose yourself, possible anonimity and most important one, the absolute lack of need of a third party which is the thing that most find intresting about blockchains usecases.
Except the most common way to do blockchain transactions are broker services which do require user information. This, combined with the fact that the blockchain is an immutable public ledger (meaning any transaction can be traced back indefinitely), and there goes anonymity.
By brokers you mean Centralised Exchanges ? If yes I agree it's an aberation as we've with recently with Russia's problems people getting banned from it because these exchanges are bounded to obey country's laws.
Everyone should leave CEXs to get on DEXs and learn about DeFi but as cool as it can be it's everything but userfriendly and as it is it'll never make it to public adoption.
About tracing transactions as long as you don't dox yourself everything people can have about a wallet being yours is suspicions and there's always services to make it shady like tornadocash or anonimity oriented blockchains
> Everyone should leave CEXs to get on DEXs and learn about DeFi
That is not going to happen, for the same reasons why most people don't dig their own wells, learn carpentry to make their own furniture, or weave their own cloth and learn how to tailor clothes.
Every complex enough system will always have centralized points, aka. gatekeepers. That is how human society self-organises.
> That is not going to happen
IT's actually being worked on, it's something sometimes refered as a "layer 3" even if it's not realy one when you look at what are layers 1 and 2 but the goal of this logical "layer" is to make abstraction of everything, make crosschain needs and moves absolutely transparent. It's one big point for mass adoption and great thinkers and workers know that and are already working on that.
>Every complex enough system will always have centralized points, aka. gatekeepers.
That's where the problem is. 3rd partys have been introduced for security reasons but are nowadays far from it and that's what some people are actually fighting for. An autonomous system where the only pseudo 3rd party is an impartial public registry
Again: Most people will not use a more complex solution when a simpler one exists, regardless of whether the simpler solution requires a central authority. Example: People used to use IRC, which is a really easy to use system. Then along came chatrooms, and then centralized messenger systems. Sure, some people still use IRC, but they are not the majority.

Which systems are "far from it"? The financial system? I get my paycheck every month, all payment processes work fine. The government systems? Elections in my country work flawlessly, tallied and protected by central authorities. The power grid? I haven't had an outage in 4 years, and the last one lasted all of 10 minutes. Public Transport in my country is affordable, well maintained and usually on time.
So it seems to me that centralized systems work just fine in the vast majority of cases.
Anonimity and privacy on internet are a right and you don't need to do shady stuff to enjoy them and outside of the immediate risk caused by doxing oneself when having a heavily valued crypto/nft portfolio I agree that it's not always needed.
It still should be an option though as when selling valuable stuff p2p some protection is always appreciated.
I don't really get the part on how selling something you own p2p makes you a third party and I don't care about the 2nd hand tickets market, I'm only intrested in a safe decentralized p2p market
I'm obviously not making a point against anonymity in general, so spare me the spiel.
> I don't really get the part on how selling something you own p2p makes you a third party and I don't care about the 2nd hand tickets market, I'm only intrested in a safe decentralized p2p market
The peers in this transaction are the event organizer and the person who ends up with a ticket. The ticket scalper is third party that "facilitates" the transaction at a cost. Essentially a broker that no one asked for.
