From what I hear from people who are, the clubs have become basically tourist traps that are unaffordable to locals and some have even been priced out of their original locations so not sure if this decision will help much.
I remember in 2015 paying 10-15€, even Berghain would be around 15-18€ and that was expensive already.
The techno scene is still pretty good music-wise if you check the line-up and avoid the new fad of celebrity DJs from the past 8-10ish years. I'm very fond of my early techno days where you could barely see the DJ from the dancefloor, they would be spinning in the shadows and the focus was dancing (this in the early 2000s so not an OG at all to the scene from the 90s, and not in Berlin).
To me personally since the big room/celebrity techno DJs took more space in the scene it has become much harder to find dancefloors like Berghain. I'm still sad for De School closing in Amsterdam, it was a very different place than Berghain but the crowd and dancefloors were very enjoyable.
Interestingly, as an expat/immigrant I've met all my local Berlin friends clubbing, and most of my friends here are German. My colleagues who don't go clubbing seem to be in little bubbles of other expats.
As a result, these people go everywhere and do consumption and outcompete everyone who is not like them. Then everything gets adjusted to their pleasure and they consume all the resources(being housing, food, entertainment etc).
Also, the supply and demand are not able to stabilize because the money moves around the globe freely but working people can't. So when a cryptobro from Russia moves to Portugal he can consume all the Portuguese resources but he can't bring fellow Russians to work and re-supply. Why wouldn't Portuguese just work harder and make buck by increasing the supply to meet the demand? Well because the cryptobro demands luxury housing, luxury food, massages, cars and cocaine but the Portuguese in the location they moved in are maybe painters, taxi drivers, chemical engineers or doctors and they can't simply start doing this new stuff.
The folks are angry with working class immigrants but most of their troubles are actually due to a-few-millionaires who are not rich enough to do substantial long-term investment but are rich enough to consume like there's no tomorrow.
The real economy is not elastic enough to handle increase in demand instantly. It takes years to train people to do the things that are taken for granted.
Think of it like the developer salaries in the USA when the money poured in, until it stopped.
Generally speaking, money is for bookkeeping among agents that produce and consume value and the production and consumption has natural speed within the laws of physics. When people who move around faster and demand stuff to consume than the people who produce, then you have local bubbles that disrupts the society.
Also, since the output of the people is finite the larger is your elite class the less stuff to consume for everyone. Better have you elites becoming elites because they dramatically increased the production of the stuff they consume(for example, they might have invented the internet and the services on it and improved efficiency of trade or they might have made great music and improved the working conditions of people who work in insulation, thus more people accepted the job etc.). If you have an elite that is growing faster than they improve the yield, then you have a parasitic class that might end up destroyed if grows too big.
