You can't compare in-person and e-commerce payments in that way. The risk for the merchant and the customer is completely different:

A physical merchant usually has a storefront in a public place that they can't abandon on a whim, a reputation to lose etc, whereas the customer is usually anonymous and mobile. This is why customers are generally ok with paying using a (to them) irreversible/final payment method, and merchants will insist on it.

In e-commerce, the risk lies almost exclusively with the customer: An online store's reputation is not easy to judge (and brand impersonation is its own risk), and even at reputable merchants, the time between order and delivery is much longer, goods can usually not be inspected ahead of time etc.

Not coincidentally, the various card schemes' rules reflect this circumstance by assigning default liability for online payments to the merchant (or their acquiring bank, in case of a fraudulent or bankrupt merchant), whereas for in-person payments it lies with the cardholder (or in case of fraud with their issuer, in some circumstances).

And you typically get your product immediately when purchasing at a physical storefront.

In the early days of eBay, it wasn’t unheard of to send out a money order in the mail, wait a month, and never get the item.
