Because once your government is the arbiter of "electrician", anyone who thinks the rules are ridiculous (they are frequently way over the top) will be marginalised (and unemployed)?
Because once your government is the arbiter of "programmer", anyone who can hack a few lines together but is only 12 and not permitted to license will be marginalised (and uneducated)?
It is getting much worse. Not only is little freedom left but it's been taken away under the guise of the exact opposite, and the façade is widely, and often violently, believed.
I've mostly plumbed, entirely wired and partially built my own house. I can see better ways to do what I did, of course, and much much worse ways to do what I did. The boiler installer I hired was, thankfully, top notch (I am ridiculously careful with gas).
Oh and I also installed the fibre, installed an ethernet and wifi router, protected it all with a firewall and integrated a server and VPN.
And I grow about ⅔ of my food.
I do all of this without being qualified to do any more than make a coffee and people who are actually 'qualified' (or, more realistically, licensed) have mostly congratulated me on my work.
Should I have done none of these thing because Whitehall thinks erroneously that I'm too stupid? Fuck those cunts. My daughter is safe, has good friends, is well fed and well educated despite their bureaucracy, not because of it.
If anyone thinks I should not have done the plumbing or the electrification, despite being unlicensed, explain why growing my own food and configuring my own internet are OK. Or try and convince my that I should sacrifice my router to my government. And if you attempt (and you will fail utterly) to do that, prepare to be told to fuck right off.
The trades are here to protect other people from me asserting my skill in electrician-ining, when I have no such skill but represent to others that I do.
Who is the ISIS of plumbing? I'm confused by that assertion.
If you screw up a router install you have no internet. Screw up a diy plumbing job...
Even the threat of it can affect what is / is not covered.
Once the government has significant power over journalism, you end up with Russian state sponsored journalism.
It's not perfect over here, and needs much improvement. Access is contingent on certain rules. It can get much worse.
