You can work abroad, just don't say anything and follow the laws. Make sure you don't spend the maximum time outside the US to be considered a resident, don't over stay in what ever country you choose to work from (90 days Schengen Zone every 180 day period), Canada is 90 days, etc. Don't even tell your employer if they let you work from home and don't require to come in.

...You realize that any moderately sized corporation will monitor things like changes in IP address correlate with changes in location for compliance purposes?

That the fines assessed against the employer for allowing work to take place that violates the terms of immigration based eork visas is quite stiff?

Unfortunately, your advice is downright terrible and simply will not work. Most of the western world has outsourced immigration enforcement onto their private employers. While it may not have been a big deal in earlier times, the mapping of the IP space, and geolocation capabilities based off of it are an omnipresent to the modern corp. We alread live in the dystopian surveillance hellscape.

What organization is going to monitor IP addresses from an IdP or VPN service log for where an employee might be sitting?

If there was some sort of suspicion, sure, but it is very unlikely an org is going to monitor logs in real time for company-wide human resource purposes.
