Aren't you a mathematician? 
What you say reminds me the old science joke about the scientists and the tin can.
What you say might be true in theory, but in practice you don't go for 1 pip per trade. And the reason why inverting doesn't work, might be that price could hit SL before it hits TP.

The reason why INVERTING trades doesn't work IS the spread.
There is no other reason.
If you want, we can speak about why people fail, how to trade profitable, how to find a positive edge, etc. But this is not the topic.
The topic is: why INVERTING trades doesn't work. You speak about mental laziness, OK, make a little mental exercise:
Imagine a broker who offers a special offer: if you fund your account with more than 9,999 dollars, you get a week WITHOUT commissions AND without spreads. You say, whoa, I'm going...

Ah yes, I get it, ASK = BID when you short then BID = ASK when you close. And BID = ASK when you go long and ASK = BID when you close it. Simple isn't it..... :nerd: 
Have you read the entire post? If I reverse all SLs and TPs TOO, when the price in the original entry hit SL before TP, in the reverse entry it would hit TP before SL, because always ASK = BID.

I'm talking about something beyond scalp ok, something that will apply to scalp swing or position trading scenarios.
Note the pic below.
When you flip the picture B starts to be the bottom and A the top of a ascending trend, but according to natural laws ( math) when you flip something you also have to flip the sign so the ascendant graph will go right back south again

INVERTING trades doesn't work because the spread, it's a fact.
......Ohhh boy the retail traders world....
Yes... It's an amazing world where you can become rich... Or lose your pants 
Anyways I'm not going to argue more this question, I will open a thread when I have time to prove how spread affect trading with these rules:
- SLs and TPs less than 50 pips.
- Execution of orders at the same time.
- No slippage (backtesting).
- More than 200 trades at year.
- Same distance of SL and TP.
- Same amount of lots in all trades.
With comparison of curves of original and reversed trades.

You are failing to understand the concept....the goal of the thread was to explain why a system that looses money will still loose money when traded inversely.
Try to swap the word speech to brain and maybe you will realise why you can't grasp the concept
Did anyone say parrot ?

When are you going to make up your mind Intensity
But that's not really important and I am going to kiss you good night - #76

I have to make a slight modification. Inverting RANDOM trades doesn't work because of the spread. Inverting trades with a true negative expectancy works perfectly well.
Your random system if traded mechanically has an expectancy of precisely ZERO.
This thread really is fascinating, but rather scary too.
even with a spread of zero, inverting random trades doesn't work...
simply because one has to know WHEN to invert i.e. maybe next time the trades are inverted the inversion loses and the original trades win...
