I took a break for about 4 months, still am somewat.
Last day of my sub I get into my house and then exit the game, sub runs out and I keep it like that for 44 (or whatever the amount of days is, I look at my emails 4 times /day).
1 day is left, I get Steam 30 day sub time, I log in the game, teleport to house plot (I was already there from last login), I step inside my house and exit again.
That takes less then 1 minute and there are 1440 minutes in one day. Better yet I counted this today and it takes me on average 25 seconds to launch client, login and get in my house and there is 86400 seconds in a day.
I'm much less a fan then you are, I don't go to fan fests, I didn't start in the beginning of time, yet somehow I know about this and also SE is friendly enough to send me multiple emails when my house demolishing is about to happen.
When you do have time to do seasonal events, then you also have time to spend less then 25 seconds to reset your house removal time.
Yes the housing system is trash and yes it sucks that you need to keep active sub time to prevent your house removal.
It's your own fault to be honest, you're describing yourself as the best fan but you don't know about this, the internet is full with info about this. Even I who's nothing compared to you're super uber l33t fan awesomeness about this game knew about it.
And to 'save' the most money in how to keep your house while being inactive you can do this:
On the last day of your sub you go into your house, then you can leave your account frozen for 44 days or whatever the counter is minus 1 day, then you get a new sub, login to the game and get in your house to reset the timer (less then 25 seconds needed) exit the game and 29/30 days later you log back in the game and go in your house (less then 25 seconds needed) you exit the game and then you keep your account frozen again for 44 days, rinse repeat ...
Edit:
Have you been living under a rock? Remember the recent nature disaster (not the current one but the one before that), It was all over on XIV stuff (on the launcher and on the webpage, ...) that auto-demolish was temporary suspended for people who had been hit and had no electricity, etc so they would not be able to come online.
Have you never once though 'what could this auto-demolishing mean'?
As a super amazing fan that's something you should have thought I think?
