it does not matter in the end if it cuts the connection to funds. you stil end up on a watchlist which means any information about you gets shared.
But, you can only know my outputs, not the inputs I used prior mixing. Ending up on a watchlist is a situation I assume it happens on
every address, as the ledger is public. Less mixing means more surveillance from chain analysis companies, whereas more mixing means they can do their job less effectively and efficiently.
by the very fact of using a mixer. your coinbase coins get highlighted on a chain analysis list as suspect just for using a mixer, which then triggers coinbase to see your withdrawal is a suspect use of funds due to entering a mixer.
Coinbase can enforce completely arbitrarily rules to their clients, as you said they might (I haven't ever read they do this, but they might) check the destination of my funds, after I withdrew them from the exchange, and act accordingly to their policy. Solution: Don't use Coinbase, because they don't treat their clients properly. Mixing is privacy, and privacy is a fundamental human right.
Note that both Coinbase and the gift card company cannot still link my funds, which wouldn't be the case if I had just send them directly from Coinbase to the gift card company.
and chain analysis also passes ALL sets of funds received from mixers. which triggers gyfts deposit of coins to be on a suspect watch list. and then when they see your delivery address and name and the coinbase details. .. boom they have linked you. and they pass that back to coinbase that you purchased a giftcard
They can't do this, for if they did, mixers would have no point. They can't break the connection of either ChipMixed or CoinJoined funds. No matter how many watchlists, pointless analysis, timestamp considerations they make, they can never be 100% certain that I have a connection with my mixed funds. Unless of course both Coinbase and the gift card store require KYC.
thus defeating the point of using the mixer, because it was the mixer that ended up triggering you being on a suspect watch list where they are actively watching you and passing your info around and sent as a sar to the government
Same thing happens if you don't mix. If you've handed over your personal data, these companies will send everything their government request about you. Whether you're a criminal or not. Because, being surveilled is non-related with being a criminal. Again, solution: Don't use services wherein you're forced to hand over KYC.
now imagine you used coinbase and withdrew and then deposited to gift without the mixer.
well you are not on an active watchlist and your details of you using coinbase+gyfts is not sent as a SAR to the government
Because, being added to a watchlist requires to have your privacy preserved. Giving up with privacy, means they can put their nose on your personal life more easily.
one is where you are put on a SARS report (government see you) and one where government do not
False. I'm either a suspect or a civilian who's opened up to full scrutiny. I prefer the former, thanks.
