I wonder, if they added 10 rows of these that would only be 4 seats per row.

I don't think the actual bucket size is ten. But I'm fairly sure that they hope to sell more tickets from the later, more expensive buckets, not from the earliest buckets. They don't plan to fly many almost-empty flights.

Also, that will just be the seat price not the whole ticket price. Try booking anything on their cheapest rates and when you get to the screen where you pick seat preferences you'll find there will never be any that are free (cheaper seats are included in the ticket price for higher priced tickets that include some luggage allowance, and on that screen you can opt to pay extra to get on/off faster or have a few mm more leg room).¹

I wouldn't be surprised if the standing "seats" don't get even the minimum carry-on bag allowance of current seats, and there is an extra charge of you want that back.

Furthermore, on top of that each of those extra passengers is an opportunity to levy any number of other extra optional charges (that might not be all that optional for many passengers).

[1] last time I looked at flights with them this seat price disparity took away a fair chunk of the price difference between the lowest rate and the next up, and if you wanted any luggage the cheaper flights were more expensive in total.

When Ryanair says "as little as" they very much do _not_ mean "but not more than". They'll be demand-priced like any other Ryanair seat.

I think you may be deeply confused about what Ryanair and co _do_.

(To be clear, all their planes are single-class; I'm pretty sure this is the case for all European budget carriers. You might as well expect a first class section on a city bus.)

Ryanair first class sounds like a comedy skit, quite frankly. You'd get access to the Ryanair lounge (a portacabin), there'd be a red carpet for you to stand on while they insisted your bag was 5mm too big, etc.
