I think the goal should not be to recreate sites in the same way, but to create a better version of the same site. Hope that kind of "freedom" will be allowed and encouraged.

Not worried in the slightest, to be honest.
At least you have a lot of the skills that are in high-demand, whether on the job market or as a founder.
Why don't you create something just for yourself once? Just something that you think you would like to use or have. Worst case, you only have something nice that you like. Best case, some other people like it, too.
