Not really something that is legal that should be illegal, but I would love to see this nonsense that corporate executives can't be held criminally responsible (the corporation is) for their illegal acts. I think it would correct an awful lot of shitty things corporations do really quickly (assuming enforcement).

Products purposefully manufactured to be unfixable. Main example being anything apple...you can't even add ram to a iMac anymore and they have the audacity to sell the lower end model with 8 gigs of ram as if that's enough when everyone knows its not. Basically selling a 1400$ piece of shit.

Everyone not having access to a 1-bedroom apartment or living space that is all theirs and affordable. So much crime is because people are forced to live with others they shouldn't be around and can't get along with in a shared living space.

Additionally, so many people are driven by the fear of homelessness so they just suck it up to their detriment until they snap and go really nuts and end up with shelter either way

Surprised to see no one has said cigarettes yet. Not only are you poisoning yourself, it's harmful to everyone else around you that has to inhale that shit.

• Lying if you're a politician. You should be in a state similar to "under oath" in court, but at all times.
• Advertising. I should have the legal right to not be advertised at. I should have the right to not have to accept advertising in order to access services, especially so if I already pay a subscription to that service. I cannot put into words how much I loath and despise advertising and advertisers. I hate them. Hate, in the real sense of the word.
• Loot boxes in video games, whatever age group the game in question is aimed at, but especially so in kids' games.
• Microtransactions in video games for anything other than non-essential/non-advantageous items, like cosmetics. Even then, their presence should upgrade the PEGI rating to adult/18, regardless of the actual content of the game. This might help prevent their inclusion at all.
• Whatever the fuck is going on in Gaza right now.
• Shielding police or soldiers from prosecution for crimes they've committed. If you stand in the way of the due process any other citizen would face, you should be heavily penalised for that. Like, the murderer soldiers who carried out Bloody Sunday are currently being protected by the British state and its lackeys, and I cannot fathom why. Cops in the US who murder people are frequently protected by unions and get to retire rather than be fired etc. All of that shit should be illegal. Get the fuck out of the way of due process.
• Naziism and related nonsense like Holocaust denial. Germany already has laws about this, but that shit needs to be legally smothered in its crib everywhere.
• Conspiracism surrounding public health issues like vaccines and masks.
• Climate denial.
• Slave labour in prisons.
• Private prisons.
• PACs and donations to PACs.
• Lobbying.
• Joe Rogan.

Arbitrary surcharges and fees. Like "5% to offset the rising minimum wage" bullshit restaurants are doing.

Popups.

Copyrights

Rich people and cops breaking the law.

Factory farming

Leveraged buyout, cutting yourself a huge check, folding the company and walking away.

Using lies, especially lying about the beliefs of important historical people or of gods in someones religion, for a political campaign is legal

Eh... where? This seems like a very location-specific question.

Being noisy in public.

Not putting your shopping cart in a corral.

capitalism

Stock trading.

I am fine with companies issuing stock and with people selling that stock back to the company. Everything else should be illegal.

MlM's. They're predatory.

Rent seeking and usury (the charging of interest)

Those chainsaw discs for angle grinders.

Alcohol. It's more dangerous than it seems.
