The waiting part is irrelevant for digital purchases and businesses where the customer doesn't immediately leave (restaurants, movies, entertainment, etc).
As for places where the customer pays and immediately leaves, businesses already factor in fraud into the current system (chargebacks, counterfiet, etc), so that's nothing new. It just has to be better. They can pay with 0-conf which is immediate. Double Spend Proofs make this even more difficult to commit fraud (Store would know within a couple seconds if customer tried/did double spend. Awkward. They would also have to do the double spend and succeed or fail within the first few seconds or it wouldn't work. Original transaction would far too propagated if they waited) Either way, double-spends on Bitcoin and Monero is extremely low especially when compared to traditional currency.
You can also stratify your risks and wait for a certain number of confirmations depending how large the purchase is.
It always seems like network effects matter so much to Bitcoiners until another currency has it then it doesn't matter (Monero is the king of privacy coins and there isn't even a close second) Funny how that works.

Privacy is all it has. It’s a one trick pony. Bitcoin is so much more. Fixed supply, adoption/network effects, fair distribution etc etc.
The good thing is that you can learn to use Bitcoin in a private way so you don’t really need monero at all.

Another option, you could use Monero-based ecash for places where you absolutely needed those "instant" transactions. Where finality was more important than self-custody
