You're saying a lot of wrong things, for starters
> Spain is ideal for a digital nomad that is willing to live in some run down area or what people call "Empty Spain".
As a tech worker, and digital nomad myself, I don't live in any "Run down area", I have a high german salary and chose to live here in Spain because quality of life is much higher than in central Europe, including Baden-Württemberg, Czechia, Poland, etc.
With this salary I've bought many properties in Spain, I can literally buy a flat near the beach for less than 20k euros. Stop spreading lies about Spain.
Just a quick look: https://www.idealista.com/venta-viviendas/alicante-alacant-a... there's 491 places for sale in Alicante with price < 60k euros, I could buy 2 in 1 year, average tech worker in Alicante makes 40k+ so they can buy one in over a year.
