You have a way to buy things anonymously right now, it's called Bitcoin. If you mean a low-fee and frictionless way, it's unclear why that would ever develop. Unless everything you earn and do is anonymous, it seems to me that the transition between the anonymous store of value and your real identity (address, bank acct) will involve friction and cost.

Bitcoin is not anonymous and is subject to flow analysis. Zcash and monero have solved this in different ways with really intriguing primitives.

ZCash uses zksnarks which are a pseudo homomorphic encryption strategy to hide payments whereas monero is using linkable ring signatures.

Generally speaking, the blockchain community has really advanced the crypto field

It is fairly trivial to to follow a BTC transaction trail and deduce the owner of a wallet.

Other options such as Monero are better for this.
