For trips I guess there will have to be a new etiquette when we stop at someones house and need to "Plug-in". Should monetary compensation be offered, if so how much?

I think the article is marketing B.S.
They'd have you think they were inventing something new. The first diesel locomotives used magnet-free excited field alternators. Detroit converted from magnet generators to excited field alternators in the 1960s. My Tesla Model S has a magnet free drive motor.
Big breakthrough in efficiency for the Model 3 was the addition of permanent magnets to the motor. The excited field consumes power that a permanent magnet does not need.
And my last point: Rare Earths are not rare.

Don't worry about it because your host won't have a 50A or greater outlet to make charging worthwhile for many years yet.
Oh, also it is illegal to resell electricity in 99% of the country. Recent exemptions have been made for commercial EV charge sites. So strictly speaking it is illegal to compensate your host.
For most homes around here 50A is 25% of the total available from the utility. Most have 200A service, big homes have 400A.

RV parks?
Apartments?
Under sub metering.
"Submetered bills are calculated by dividing the net total charges for electric consumption, plus applicable tax, by the total number of kilowatt-hours to obtain an average cost per kilowatt-hour. The average kilowatt-hour cost shall then be multiplied by each tenant's kilowatt-hour consumption to obtain the charge to the tenant."

I guess the best thing to do is when he visits you with his gasoline/diesel vehicle go ahead and fill up his tank. That is what people did in remote areas before filling stations were everywhere and you lived very remotely. I learned this from the tour guide in a remote Lake Tahoe Nevada Mansion when guest from the California coast would visit. (Just a hundred years ago . . . .)

Texas has an unusual situation. The rest of the country resale of electricity is forbidden specifically to address the landlord who decides to add a markup for tenants. Furthermore the state doesn't like making more work for itself so it grants a monopoly on the sale of electricity to utilities.RV parks?

RV parks may not bill for electricity but may bill by the hour for the camping site which includes electricity. Same as for hotel rooms. In much of the country Tesla bills by the minute for the parking space at Superchargers because they can not bill by the kWh.

Who controls the price limits of re-selling of electricity at a EV charging post in or the rate per minute to park at a charging post?

Billing procedures are easy to change.

Ford claims to be part of "America's largest charging network", Electrify America. Locate A Charger looks quite lame compared to Tesla Find Us Superchargers.
Based on "80A at 240V puts 30 miles of range in the battery per hour" I estimate the Lightning consumes 0.64 kWh/mile. Electrify America bills $0.31/kWh after $4/month membership fee. Ignoring the membership fee this is $0.20/mile. Compared to $3/gallon this is cost equivalent to 15 MPG.
Some sources state the Lightning will add 54 miles in 10 minutes at a 150 kW DC fast charger. Or 15% to 80% SOC in 41 minutes (which is virtually same as 54 miles in 10 minutes if assuming the 300 mile battery). 10 minutes at 150 kW is 25 kWh. 54 miles on 25 kWh is 0.46 kWh/mile. So there is a lot of guesswork yet.
At home my utility charges just under $0.10/kWh so the 0.64 kWh/mile cost equivalent to $3/gallon is 45 MPG. Or about 30 MPG if gasoline was $2.00/gallon.
There is no economic justification to purchase a Lightning for routine long distance travel. The purpose of Tesla Superchargers is not to replace gasoline stations but to facilitate long distance days for relatively rare situations. However there is a good argument when one can charge overnight at home or business.
