The most obvious tagging scheme for a world wide database like OSM would be
to use the commercial classification system in effect in a particular
jurisdiction.

In the U.S. that's NAICS, the U.K. has one, the EU and practically every
country in the world has one or uses on of the broader ones. The U.N. has a
very generic one. And there are published crosswalk tables and utilities
between the different systems.

They are all hierarchical, i.e. they have very very broad simple generic
categories at the top ( 20 for NAICS ) but also allow one to drill down to
the very, very specific - and the common search engines will provide the
detailed label with a simple query like Googling "NAICS Code NAICS code
bubble tea stand" gives "NAICS Code 722515 - Snack and Nonalcoholic
Beverage Bars",  '... establishments primarily engaged in (1) preparing
and/or serving a specialty snack, such as ice cream, frozen yogurt,
cookies, or popcorn, or (2) serving nonalcoholic beverages, such as coffee,
juices, or sodas for consumption on or near the premises. These
establishments may carry and sell a combination of snack, nonalcoholic
beverage, and other related products (e.g., coffee beans, mugs, coffee
makers) but generally promote and sell a unique snack or nonalcoholic
beverage." with examples.

They also provide links to alternative and related, more general, and more
specific categories. Even if someone goofs a designation, the goof will
usually still be very close to the actual one.

Also, to some degree, usually the code(s) for a particular business is
public record at the municipal, county, state/province, and national level,
it's on their posted business license, it appears on a roll or listing
somewhere. If the business is ad hoc or unlicensed, it's trivial to get the
classification by looking up the code for a similar licensed business.

It accommodates the very common situation where an establishment provides
multiple levels, like manufactures cabinets from raw materials, ships them
and distributes them wholesale regionally, and retails them over the
counter to individuals from their showroom.

The benefits to data providers and consumers are fairly obvious.
