Depending on the country, you may be able to work remotely while on a tourist visa. This is true, for example, in Mexico. The tourist visa allows you to stay in the country for up to six months and you aren't allowed to work for a Mexican company but they have no issues with you working for a company in another country.

Many times they're actually "temporary visitor" visas or something like that. Which, as you say, typically prohibits working for a local company, otherwise use local resources, etc. But I've attended business events all over the world. With just a few exceptions, e.g. China, there's never been any question of getting some special visa--which usually requires letters of introduction and so forth--to do whatever combination of business and pleasure I'm there for.

That said, I'll note that e.g. Indonesia 30 day visa-on-arrival seems to theoretically be only for non-business purposes but when I've gone there's never been any question of using anything else.
